Eric Bury, a mild mannered Englishman, is told by his boss that he must take a mandatory vacation to ease his workaholic ways. After a brief family meeting to discuss possible scenarios, Eric decides on a "family camping trip", as this may be the last vacation with his teenage children before they leave the nest. So he takes his wife, daughter and son on a camping holiday to Florida. Once the family arrives at Adventures Unlimited Campground in Florida, Eric is plunged into a world of escalating sexual debauchery, religious ecstasy, human sacrifice, sadistic policemen, dwarves and one philosophizing old man, as this dark comedy takes the family on an outlandish ride.
