Simon is the king of the Danish art scene. He is successful and rich, has a beautiful wife and a young mistress. Out of the blue his son Casper, whom he never knew, shows up on his doorstep. Casper, a world-famous street artist who goes by the alias The Ghost, takes everyone in his father’s posse by storm. This provokes and challenges Simon deeply, and the scene is set for a relentless father-son battle fought with brush and spray can. However, contrary to all expectation, the two of them slowly begin to build a relationship, and Simon starts to reconsider himself as a human being, husband and father.
