Ally Darling is realizing she's a little lost in life. Her latest romance has just fizzled out, and she's just been fired from her marketing job. Then she reads an eye-opening magazine article that warns that 96 percent of women who've been with 20 or more lovers are unlikely to find a husband. Determined to turn her life around and prove the article wrong, Ally embarks on a mission to find the perfect mate from among her numerous ex-boyfriends.
