The work hard/party harder gang is back for another summer in a brand new weekend house in the Hamptons with some familiar faces and surprising changes. Newly single Lindsay happily passes the "house couple" torch to Kyle and Amanda and two new friends join the group to make the summer family complete. Things get off to a rocky start when room selections occur without everyone's input and tempers flare even worse when the house kickoff dinner turns ice cold. Then as Stephen prepares to attend Gay Pride back in the city he struggles with a decision to invite Carl for support. Meanwhile, Lindsay enjoys her freedom by having her way with a man on horseback at a polo event, as Lauren and new housemate, Danielle, navigate their complicated feelings about sharing a summer house with their common ex, Carl.

Tensions are running high in the house after the craziness of the 4th of July party, and Lindsay finds herself in the middle of the drama after Lauren's cake-to-Carl's-face meltdown. The crew sets off for a sunset sail and beach bonfire, where these tensions boil over into drama of epic proportions. After a short-but-busy week at work, the housemates return the Hamptons, where Kyle and Amanda's relationship faces setbacks. In an effort to smooth over all the rifts and tension in the house, Danielle gains her housemates access to a very special place in the Hamptons with hopes that it will bring them all back to harmony.
