今天是情人节,TOM有个计划,他准备和朋友举办个PARTY,用惊喜向他的爱人求婚~本来很好的事情,可是反而却越变越糟。Tom plans to surprise Sara with an engagement ring, and he's asked his four best friends to witness the popping of the question at his place on Valentine's night. Trouble is Sara's left him a "Dear John" letter and will be by soon for her suitcases; plus, thinking it's a party, Tom's friend Sal has invited five women who were at his bar to come too. First the men talk - about women, sex, love, and homophobia (Tom's pals include a happily married guy, a gay man newly engaged, a metrosexual, and Sal, an inveterate player). Then the women arrive and argue in the loo about men and sex before joining the boys for talk, alcohol, and hookups. But what of Sara, and what of love?
