Rachel (Ginnifer Goodwin) is a talented attorney at a top New York law firm, a generous and loyal friend, and, unhappily, still single-as her engaged best friend Darcy (Kate Hudson) is constantly reminding her. But after celebrating her 30th birthday, perpetual good girl Rachel unexpectedly ends up in the arms of the guy she’s had a crush on since law school, Dex (Colin Egglesfield)...who just happens to be Darcy's fiancé. As one thing leads to another in the frantic weeks leading up to Darcy's wedding, Rachel finds herself in an impossible situation, caught between her treasured friendship with Darcy and the love of her life. Meanwhile, Ethan (John Krasinski), Rachel's constant confidante and sometimes conscience, is busy evading the affection of Darcy's hopelessly love-struck friend Claire (Ashley Williams) while harboring a secret crush of his own; and the charming and irrepressible Marcus (Steve Howey) has designs on Rachel that don't necessarily exclude any other woman who catches his eye. — (C) Warner Bros
