Du Pappa (English title Daddy Blue) is a 1994 Norwegian film about a teenage boy and his troublesome relationship with his dad and with a girl he befriends while running away from home on a small sailboat.
Wanting to get away from his parents, he steals a sailboat, vaguely envisioning looking up a girl he once knew a bit down the Oslofjord.
LP is sullen and withdrawn; however, the confident and well-versed girl thaws him as they continue on their sunny escapade of the Oslofjord archipelago.
Then LP's father (played by seasoned Norwegian leading actor Nils Ole Oftebro) appears and demands an end to the adventure.
LP is determined not to submit to his father's authority, leading dad to board the boat and join the young couple.
