John and Jeremy, single in their mid-30s, mediate divorces in D.C.; their summer social life consists of crashing weddings (always with a back story) to meet young women for a one-night stand. As John thinks about growing up, Jeremy convinces him to go to one more, for the daughter of the Treasury Secretary. Each catches the eye of a daughter of the host. Jeremy scores with Gloria, who proves to be a psycho clinger; John wants real romance with Claire, but she has a boyfriend, a privileged hound.
