Three families compete for a camping spot during a busy Fourth of July holiday weekend.

17-year-old Joshua "J" Cody moves in with his freewheeling relatives in their Southern California beach town after his mother dies of a heroin overdose. Headed by boot-tough matriarch Janine "Smurf" Cody and her right-hand Baz, who runs the business and calls the shots, the clan also consists of Pope, the oldest and most dangerous of the Cody boys; Craig, the tough and fearless middle son; and Deran, the troubled, suspicious "baby" of the family.
