Twelve-year-old Lucas Roosen (Noèl Gabriel Kipp) and his family live together in the daily grind. Until an April Fool's joke by their Chinese exchange student Xi Zhou (Max Zheng) gets completely out of hand and catapults them out of their well-worn structures. What is actually a harmless prank becomes the starting point for a crazy chase that brings haphazard policemen, gangster rappers and musclemen onto the scene, exposes a protection racket and jeopardizes a love affair.
