The Wave: How a History Teacher Turned German Teens Into Nazis in Five Days

What if I told you that a history teacher could turn a group of ordinary German high school students into fanatical Nazi loyalists — in just five days? Would you call that science fiction, or reality?

Dennis Gansel, director of The Wave (Die Welle), opens with a premise that sounds like dark comedy. The first act follows a middle-aged man speeding a beat-up car down a small-town highway, blaring rock music so loud passersby stare. He pulls up at the high school gates, steps out — buzzcut, floral shirt, jeans, eyes half-bored half-mischievous — and walks in. This is Rainer Wenger, the school’s history teacher.

No one could have guessed that this man, who looks thoroughly unreliable, would spend the next five days personally manufacturing a disaster that would engulf the whole school — and himself, and his students.

The Five-Day Experiment: What One Teacher Wanted His Students to “Understand”

The school’s activity week gave every teacher a chance to pick a topic related to “state systems.” Rainer had his heart set on anarchism — he’d studied in Berlin, taken part in left-wing movements firsthand, and considered himself the perfect man for the job. But when he walked into the teachers’ lounge, another teacher had already claimed anarchism.

As a backup, Rainer accepted the topic no one wanted: “dictatorship.”

Monday morning, he dragged himself into the classroom. The students trickled in, listless and half-asleep — this class wasn’t required. They showed up for easy credits, and because Rainer was known to be an interesting guy. Rainer wrote the word “dictatorship” on the blackboard, turned around, and asked: “What is it? Let’s hear something — you chose this topic.”

A bespectacled boy joked, “Teacher, dictatorship is a tailor who works alone!” The whole class laughed.

Rainer knew that wasn’t an answer. A more serious student offered something closer: “Tyranny.”

So Rainer began. The word comes from Greek, he said — it means “self-rule.” A government made of one person or a collective, holding enormous power, free to rewrite laws. “Can anyone give me an example?”

A boy said, “The Third Reich.” Another student cut in right after, bored: “Here we go again. Fine, Nazis were evil, Hitler should’ve died. It’ll never happen again anyway. The Nazis weren’t our generation — why are we supposed to carry guilt forever?”

Rainer asked, thoughtful: “So you think dictatorship can’t happen again in Germany?”

A student shook his head: “No way. No popular support.”

Rainer didn’t argue. But he was already thinking — as a history teacher, I can lecture them a thousand times about how the Nazis rose to power, but I can’t make them feel it. Maybe I could run an experiment. Right here in this classroom. Five days. Let them see it happen with their own eyes.

Day One: The Magic of Discipline

When the students came back from break, they found the classroom rearranged. The loose circle of small group tables was gone. Every desk now faced the blackboard, lined up in neat rows.

“We can be flexible this week — try something new. Anyone object?” Rainer asked. The students perked up at the word “something new.”

“What’s the basic prerequisite for a dictatorial system?” Rainer asked.

A boy who normally never studied shot his hand up first: “A Führer!”

Rainer smiled. “‘Führer’ has negative baggage these days. More accurately — every autocratic system has a core leadership role. In this classroom, who holds that role?”

“You do, obviously,” someone called out.

Rainer stepped into the part. First, respect: during class, students were to address him as “Mr. Wenger,” not the casual “Rainer” they’d used before. Then discipline: correct posture. To answer a question, raise your hand — and speak only after being called on.

“That’s one key feature of autocracy — discipline,” Rainer said. “Now, what kind of social conditions make it easy for autocratic systems to take root?”

No one shouted out. Every hand went up — silently, waiting to be called on. The student who was called stood, and answered concisely.

“High unemployment and social inequality.”

“Runaway inflation.”

“Collapse of trust in institutions.”

“Extreme nationalism.”

Day one ended with this almost startling shift.

Days Two to Three: The Allure of Belonging

Tuesday. When Rainer walked in, every student was already seated properly, and they greeted him in one loud, unified voice. The sound made Rainer jump.

He had a new idea. He told everyone to stand up and march in place. “Left, right, left, right — just follow me and feel something.”

At first they were confused. Gradually, their steps fell into lockstep, their faces brightened. Rainer stopped and asked: “Feel it? All of us moving together, becoming one. Resonance like this can collapse bridges — that’s the power of the collective. There’s another reason for this exercise too: Wieland’s class is right below us. Let’s make our enemies eat ceiling dust!”

The students threw themselves into it — faster, harder — spontaneously united against a common “enemy.” Wieland and his students downstairs were just quietly doing their work, listening to the thunder overhead, utterly confused.

Next, Rainer rearranged the seats again. He broke up the cliques that had formed naturally, pairing high-achieving students with struggling ones so they could help each other. “One person’s strength is limited,” he explained. “When everyone stays independent and competes with everyone else, it turns into every-man-for-himself. I believe firmly: only together do we become stronger.”

Then he suggested a uniform for the week. The school didn’t have one — so everyone should wear a plain white shirt, something anybody could afford, with jeans, something everyone already owned. One student got it immediately: uniforms erase individual differences. No one shows up richer or poorer than anyone else. No one competes on looks or clothes. Here, everyone is equal.

Wednesday. Sure enough, everyone showed up in white shirts, sitting neatly, waiting for Rainer. Rainer himself wore one — but unlike the others, he was now the most powerful person in the room.

That day, Rainer asked them to name their group. The vote came back: Die Welle. “Action forges power,” Rainer said. “What good is an idea if you don’t act on it? I want you to be creative — for The Wave.”

And so it began. Artists designed the logo. Computer kids built a website. Arts-and-crafts types made stickers and postcards. If you had no skills, you could contribute money. Everyone — talented or not, rich or poor — found a place to belong inside The Wave.

Day Four: The Hand Sign, Going Viral, and Exclusion

By day four, they’d even invented a greeting. Arm across the chest, sliding from one side to the other like a wave. The Wave members were giddy with it — it was a visible marker, something that separated them from everyone outside the group.

Slowly, The Wave swept through the entire campus. Students from other classes started joining — what we’d call today “going viral.”

Why did these kids throw themselves into it with such fervor? The story is set in early-2000s Germany. The Cold War was over. Globalization was surging forward. People woke up to find themselves in a wide-open new society — breathing free air, yes, but also anxious and disoriented. Consumerism had washed away traditional values; new values hadn’t hardened yet. Individualism reigned. “Everyone only thinks about themselves.”

As one student put it: “Today’s kids want to rebel, but there’s nothing to rebel against. We lack a goal that could pull us together.”

Philosopher Hannah Arendt once wrote that human isolation and loneliness are preconditions for totalitarian rule.

And at home? The adults — their parents — were just as lost as their kids in this new world. They often neglected their children’s need for guidance — and that neglect deepened the kids’ loneliness, making them even less sure what their lives were for.

The Fall and Resistance of Three Students

The film doesn’t paint every student with the same brush. Inside The Wave, three names stand out: Karo, Tim, Marco.

Karo comes from what looks like a warm, supportive family. She has Marco, a boyfriend who loves her. But she still feels alone — because no one truly understands anyone else. Her parents let her do everything. Her little brother is a troubled kid, and her mother thinks “kids need to find their own boundaries.” Karo painfully realizes she can’t find a sense of responsibility at home.

So she throws herself into The Wave, hoping to contribute to something larger, to find direction. Then Rainer requires everyone to wear a white shirt. Karo walks in wearing a red T-shirt — she thinks white shirts look terrible on her — and in a sea of white, she’s the only odd one out. Her classmates shut her out. Even Rainer ignores her.

Karo starts to doubt the group. She realizes her individuality has no room here. She goes to Rainer and asks him to stop. “There’s only one day left in the activity week,” he says, dismissively. “We have to finish what we started.” Karo warns him things have gone too far. His answer: “Then you’ll have to switch classes.”

Thursday night, while everyone else is at a bonfire, Karo sneaks back to school. She prints a thick stack of flyers and leaves one at every classroom door. She refuses to give up independent thought just to fit in — and for that, she becomes an outsider within the group, gets pushed away by classmates, argues with her boyfriend, but never loses her ability to judge the world around her.

Tim is a small boy with freckles, shy and quiet. His father is strict; his mother, submissive. To avoid getting bullied at school, he sometimes buys marijuana to bribe the school thugs. He wants friends, but they look down on him and call him “weak.”

After joining The Wave, Tim suddenly has companions. The teacher notices him, praises him. Most of all, he feels a new confidence. One day the thugs come asking for weed, and Tim says no — without hesitating. A scuffle breaks out, and two other Wave members show up and chase them off. “Call me next time you have trouble,” they say.

Tim throws himself into The Wave with desperate devotion. He burns all his brand-name clothes. On Wednesday night, when he and some classmates are spray-painting Wave logos around town, he climbs the tall scaffolding of the town hall and paints the logo on the giant curtain at the top. On Thursday after school, he shows up at Rainer’s house begging to be his personal bodyguard. Friday morning, when Rainer steps out to get the newspaper, he finds Tim curled up by the front gate — he’d spent the night there.

Tim had come to equate everything he found in the group — purpose, strength, dignity — with The Wave itself. When The Wave was about to end, all of that went down with it.

Marco comes from a broken single-parent family. He envies Karo’s home life, craves attention. The only place he can blow off steam is the school water polo pool. Joining The Wave finally gives him a sense of belonging. But Karo’s open opposition, her attempts to stop everything, make Marco a target inside the group. He can’t convince Karo to join. Karo can’t convince him to open his eyes. A crack forms between them.

Friday afternoon’s water polo match. Wave members control the whole venue — no one gets in without a white shirt. The game turns violent, players shoving and splashing. Karo and a classmate sneak in to distribute flyers. One Wave member drags an opposing player into the water to fight. The match is called off. That night, Marco and Karo argue. It starts raining. Marco slaps her.

The Final Three Days: From Teacher to Prisoner

Friday night, Marco shows up at Rainer’s door, soaking wet. “I did something terrible. I love Karo, but I hit her. All this discipline stuff — it’s fascism! You have to end it!”

That same night, every student gets a group message from Rainer: Tomorrow, noon. Assembly hall.

Saturday. The assembly hall. Rainer walks out slowly. The white-shirted crowd rises as one. Arms slide across chests. The sound — a unified rustle — crashes through the hall like a wave.

Rainer starts reading student reflections. All positive: equality, meaning, purpose. One student even writes, “The Wave made me a better person.”

So Rainer delivers a rousing, inflammatory speech. Germany is declining, he says. We’ve lost to globalization. High unemployment, inequality, social injustice — these are the very conditions we discussed in class, the ones that make totalitarianism possible! “The Wave is the only solution. If we stand together, we’ll make history. Anyone who tries to stop us — the Wave will swallow them!”

The crowd roars. Rainer shouts on: “The Wave will sweep across all of Germany —”

Then Marco stands up, furious. “Can’t you see what he’s doing? He’s manipulating you!”

The hall is a boiling white sea. Marco is a small boat tossed alone on the surface. Five or six hands grab him and drag him up to the stage.

“What do we do with a traitor? If I told you to kill him, would you do it? Or we could hang him, torture him, until he breaks!”

The students freeze. The fever breaks in an instant. Rainer’s tone shifts: “This is exactly what a dictatorial government would do! Do you realize what you almost did?”

Everything that just happened — it was a planned performance, between Rainer and Marco. He wanted the students to feel fear themselves, to understand what dictatorship actually means.

“Remember Monday’s question? What we’re doing right now — that’s fascism.”

Rainer apologizes. He announces the class is over and tells everyone to go home and think. But he didn’t expect how far things had already spun.

Tim walks up onto the stage with a pistol and blocks the exits. A student says it’s a toy — then a shot rings out. The student falls. Tim collapses, screaming through his tears: “The Wave is everything I have!”

Rainer walks toward him, into the line of fire. “If you shoot, Mr. Wenger is gone. The Wave has no one to lead it.”

Tim’s arm lowers. Tears stream down his face, twisted with pain. Then — in one sudden movement — he raises the gun, puts the barrel in his mouth, and pulls the trigger.

After the Wave Passes

Outside, under pale, stark sunlight, the white-shirted students mill around campus — silent, crying, in shock after the catastrophe. Three vehicles pull in: an ambulance, a hearse, a police car.

Rainer sits in the police car. He lifts his head from his hands. For a moment, his confused face looks like it has just seen something he can never unsee.

The Takeaway: Independent Thought Is the Antidote

This brutal ending lays bare the film’s most important lessons.

Once totalitarianism finds fertile ground, it takes on a life of its own. When people surrender the charm of the collective and give up independent thought, they lose their capacity to judge. They obey blindly — until disaster strikes. Tim is the perfect example. When he equated “The Wave” with everything that gave his life meaning, the Wave’s collapse meant his collapse.

But independent thought is a line you can still hold. Karo is the model. She couldn’t convince her boyfriend — but it was her refusal to give up her own individuality and her own judgment that let Marco, in the end, wake up and stand up and say, “Can’t you see what he’s doing?”

And finally, Rainer himself. As a teacher, his intentions were good — he wanted his students to understand, not just know. But he made one fatal mistake: he thought he could always stay outside the experiment, always remain the one in control, always be “Mr. Wenger.” Power and adoration are drugs too. His wife put her finger on it in an argument: “You enjoyed being worshipped by your students, so you gave up rational thought.”

It took only five days to turn ordinary students into fanatical Nazi loyalists. And it took only one small thought — “There’s only one day left. We have to finish what we started” — to turn a good teacher into a prisoner of his own creation.

The roots of totalitarianism are closer to ordinary people than we like to believe.
