Albert, a French Resistance hero, is on a mission to get hold of an elixir capable of giving strange abilities to whoever drinks it. Unfortunately, the potion ends up in the hands of four teenagers, who do not intend to team up, or to help Albert.

After failing to contact the head of Resistance, our heroes have no other choice but to steal Colonel Dietrich’s papers in order to cross the barricades. Undercover in the brothel where the Nazi officer spends his evenings, the teenagers and Albert will have to learn to cooperate to fulfill their mission.

Finally arrived in the Free Zone, our heroes must cross a bridge that was destroyed by the Communists as a precaution. They will have to fraternize with them in order to make it to the rendezvous point with Lupin, Albert’s best friend. As they stop at an inn, intimacy starts growing.

Safe in a Hexagone Network hideout, our heroes must undergo medical tests before they can be released. Unfortunately, there’s a traitor among the Resistance and the Troublemakers fall into a trap. They try to escape, but must face the limits of their powers and the team is divided.

Albert finds Lorraine with the Communists, and he will have to prove that he isn’t the traitor. Meanwhile, Manu and Solange are on their way out of France. As they’re getting more and more intimate, Solange is caught by Shäffer and Manu flees abroad.

Pierrot is held by the Nazis. He must resist Dietrich’s tortures to find out the Resistance’s secrets. Schäffer seems to be kinder, and reveals to Pierrot the full extent of his power and how to master it.

Albert and Lorraine are tracking down the traitor responsible for the Hexagone Network’s downfall, but discovering his identity might be much more devastating than they thought. Meanwhile, Schäffer tries to win back Solange, who ends up giving in...

Finally together again in the Hexagone leader’s house, Albert, Lorraine and Solange put together a plan to free Pierrot. But Manu isn’t far, and may have a role to play...

The troublemakers are as united as can be. Freedom is near, and they are waiting at the Leader’s house for the plane that will take them to England. But quickly, doubts arise regarding the last Hexagone members’ reliability… And the Resistants find themselves surrounded by the Nazis.
