18-year-old Casper wants to reach the top, no matter what. Carrying out small-time break-ins for petty thug Jamal around his downtrodden neighbourhood in Copenhagen's northwest, Casper soon graduates to big-time heists for gangster Björn. All goes well until Jamal's gang decide they want revenge. But what starts as trivial punch-ups soon escalates into a bloody gang war, with Casper at the very centre of the conflict. This leaves him to question his own ruthlessness and morality once his younger brother is dragged in to the clash.
