Das Alibi plot
Hannah is sixteen and hopelessly in love with Till, an insufferable, beardless bastard. During a school trip, Till, Christoph and Sören rape a pretty classmate in the shower and knock her unconscious. She turns out to be dead and the boys dump her into the sea, from which she is fished out the next day. Unbeknownst to the trio, Hannah witnessed their misdeed and the amorous Hannah decides to provide Till with an alibi, getting more and more entangled in the case and becoming a suspect herself. The police investigation is led by Hannah's father without them both knowing it initially, as he had lost track of her years ago.
