A Good Old Fashioned Orgy (2011)

Eric (Sudeikis) is a thirty-something party animal famous among his close circle of friends for his lavish summer theme parties at his father's swanky Hamptons pad. But when members of the crew start settling down, and Eric's dad announces plans to sell the beach house, Eric decides it's time for one last bash to go out with a proverbial bang - a good old-fashioned orgy.
