Ally Darling embarks on a quest to find the best "ex" of her life, by any means necessary, when she reads a magazine article warning that people who have had 20 or more relationships have missed their chance at true love. Ally’s hunky new neighbor Colin (Chris Evans) helps her track down her exes, in exchange for Ally helping Colin avoid his.
