Eric (Jason Sudeikis) is a perpetual adolescent who lives to party, holding lavish theme-events with his friends using his father's large house in the Hamptons. On July 3, Eric throws a white trash bash party attended by his friends Sue (Michelle Borth), Adam (Nick Kroll), Mike (Tyler Labine), Laura (Lindsay Sloane), Kate (Lucy Punch), Glenn (Will Forte), Doug (Martin Starr) and his girlfriend Willow (Angela Sarafyan), Alison (Lake Bell) and her boyfriend Marcus (Rhys Coiro). Eric meets Kelly (Leslie Bibb) at the party. The following morning, Eric's father (Don Johnson) arrives and informs him that he is selling the house. The next weekend, the group arrive back at the house and find it for sale by Dody (Lin Shaye) and Kelly.
