Kasper's parents are divorced. Every other weekend he takes the train between Jutland and the capital with a group of other children. Kasper finds making friends difficult, but his talent for rapping gives him a strong connection with another outsider, Tobias, who makes music on his computer. On the train the two boys make a rap CD for a pretty girl named Marie. It turns out that her father is a famous judge on a popular talent show on television. That opens up new opportunities for boys, but it also creates jealousy among the popular kids in the railway car.
