Two married couples drive out to a campsite for an intimate high school reunion, looking to have some innocent fun and reminisce about the good old days. When dysfunctional wild cards Frank and Marcy unexpectedly show up, however, the weekend retreat quickly turns perverse. The group's infidelities come to light, and while some still aren't over former flings, others are looking for payback. Once the partying begins, adultery ensues...but when the cheaters start to disappear the tension escalates and fingers are pointed during the search for the missing sweethearts.
