The secret to a happy marriage? According to twentysomethings Vince and Cameron, it's staying together while following the title code to occasionally stray into "greener pastures." They share their philosophy with their best friends, newly engaged Ben and Kate, but a trip to a lavish Hamptons party will test the rules...and each couple's relationship. Lively and sexy bedroom romp stars Jesse Bradford, Tammin Sursok, Virginia Williams, and Michael McKean. 94 min. Soundtrack: English.
