Hyper-organized and aggressively controlling Kathryn throws a 'back to nature' camping weekend in honor of the 45th birthday of her mild-mannered husband, Walt. What should be a relaxing celebration in the wilderness becomes a test of friendships and marriages when other couples arrive at the campground. The weekend morphs into a series of arguments, confessions, animal intrusions, emergency-room visits, and woman-on-woman crime that won't soon be forgotten.
