Over the course of one raucous night at a seaside wedding, seven close friends - all members of an eclectic college clique - assemble to watch two of their own tie the knot. Laura, maid of honor, and Lila, the golden-girlbride, have long rivaled over the groom, Tom. Friendships and alliances are tested, and the love triangle comes to a head the night before the wedding, when the drunken friends frolic in the nearby surf and return to shore... without the groom.
