The four friends Musti (Reza Brojerdi), Hannah (Lea van Acken), Yannick (Jerry Hoffmann) and Tom (Lucas Reiber) could not be more different. But they have one thing in common: They are all pretty nerdy misfits who only just survived school thanks to their mutual support. For graduation, they want to prove it to everyone and promise nothing less than the craziest party of the year. However, the closer the legendary party gets, the more the friends realize that there seems to be something between them. Be it unspoken feelings, hurt pride or fear of the future. When the big day of the party finally dawned, the four of them were no longer just about celebrating, but about saving what is most important to them: their friendship!
Sebastian (Mark Waschke) is a physics professor at the University of Jena and dealing for years with parallel universes. Meticulously, he tries to prove its existence scientifically. His college friend Oskar (Stipe Erceg), professor of theoretical physics at CERN in Geneva, smiles at Sebastian's firm belief in parallel universes and the many-worlds theory. In order to devote himself to the evidence in peace, Sebastian brings his son Nick to a summer camp, while his wife Maike (Bernadette Heerwagen) is on vacation in the mountains. At a rest stop Nick disappears out of the car and so for Sebastian a nightmare begins. Increasingly he is loosing more and more control. What really happened? It is fatal to his own theory? And who is this mysterious Schilf, which occurs abruptly in Sebastian's life?
