Wedding bells are bringing together a group of old friends as well as reawakening some old rivalries in this comedy drama. Lila Hayes (Anna Paquin) and Tom McDevon (Josh Duhamel) first met when they were attending the same Ivy League college, and they became part of a circle of close friends who called themselves The Romantics.

Six years after graduating, Lila and Tom are getting married, and their friends are seeing each other for the first time in years as they come together for the wedding. Laura Rosen (Katie Holmes), Lila's college roommate, has been invited to be the maid of honour, but while they're close friends, Laura has a secret - she had a fling with Tom while he was dating Lila and she knows they still have feelings for one another.

As the wedding day arrives, the occasion (and an open bar) brings some old skeletons out of the closet, especially as Lila's brother, Chip (Elijah Wood), confesses his attraction to Laura.
