Betsey, Bobby and Cal are best friends from college who haven't been in the same room since their graduation 10 years ago. Now Bobby's getting married, Betsey's hosting the celebration at her cabin in the Berkshires and Cal is the best man. With Bobby on the verge of becoming a husband, Betsey married with two kids, and Cal vehemently opposed to the institution of marriage, the fireworks are unforgettable when these three friends reunite over one July 4th weekend.
