Three women, three birthdays and one unforgettable night that will change their lives forever. One night in San Francisco, three women make a birthday wish believing it can't possibly come true. Liz is turning thirty. A successful nurse, she has a good career, but no man to share her life. All her friends are married, and she's alone, still trying to outrun a tragedy from her past. Then she meets a handsome stranger. Carole, a corporate wife, is staring down forty candles. Having grown up poor, she worked hard to get ahead, but when her kids bail on her birthday, and she discovers her husband with another woman, she realizes that she may have nothing at all. She goes back to where it all began, the mother she left behind, and the man whose heart she once broke.
