Rachel (Ginnifer Goodwin) is a smart, talented and driven attorney at a top law firm in New York. She spends most of her free time with her best friend Darcy (Kate Hudson), who is a bride-to-be … to-be married to Rachel’s longtime crush from law school, that is. Friendships are tested when a series of unexpected events lead Rachel to sleep with Darcy’s fiance (Colin Egglesfield) after celebrating her 30th birthday. Rachel sucks her good friend Ethan (John Krasinski) into the mess, and the three of them try to clean things up while Darcy finds something old, something new, Something Borrowed and something blue.
