A rowdy teacher accompanies a class trip to Thailand to recover some diamonds accidentally sent there and restore the school's reputation.
The class of a normal German school travel to a small village in Poland near the sea where no action of any kind can take place. Due to this fact they focus on themselves. Especially one girl, Isa, has to choose between two boys who are fighting against each other. Then a final "test" is made to come to a decision... a test with final results.
It's double trouble when fate and an ill-executed diamond robbery throw Mel and Franny together in a race and chase against time.
