Sommer (2008)

Because he can't accompany his father, a German army officer, on his next deployment in Somalia, 15-year-old Tim has to move in with his grandmother on the North Sea island of Amrum. There, the cool skater from Berlin, who seems to magically attract problems, immediately loses his reputation as a freak and difficult outsider. Only chubby Eric, who suffers teasing and attacks from the surfer clique around rich Lars, stands by him. When Tim also falls in love with pretty Vic, Lars' girlfriend, a fight is inevitable.
