Anna Faris plays “Ally” in this edgy romantic comedy about a woman who reads a magazine article claiming that “women who have had 20 or more partners in their lifetime have a good chance of staying single for life.”  After counting the men in her own life, Ally begins to lose hope of every getting married. Vowing not to exceed her current number, she enlists the help of her handsome neighbour (Chris Evans) and becomes obsessed with tracking down her old boyfriends to see if she may have missed “the one.”
