Roxy (Luna Wedler) is new to the class and turns all boys' heads. The quick-witted 17-year-old has just flown from her old school and is in no mood for the upcoming class trip to Berlin. On the bus she befriends the sensitive outsider Cyril (Aaron Hilmer), who surprises her with his wit. Cyril is immediately fired up, but doesn't count on chances because he is ridiculed by everyone because of his big nose. Roxy also seems to be more interested in the attractive Rick (Damian Hardung). Stupidly, he's a mental low flyer and doesn't get out three words in a row. When ripper Benno (Jonas Ems) also keeps an eye on Roxy, Cyril starts a daring coupling action to protect Roxy from Benno's wrong game: He writes cool songs and romantic SMS for Rick, so that he scores highly with Roxy. But who will win "the most beautiful girl in the world" in the end?
