Elliot Sherman (writer-director Michael Showalter) is a nice guy who's tired of finishing last, but he's at a loss to explain his bad luck with the ladies. His most recent heartbreak at the hands of a pretty magazine editor (Elizabeth Banks) has helped him swear off women forever and declare himself a bona fide "Baxter." But advice from a plain-talking girl (Michelle Williams) could be just the thing he needs to become a marriageable leading man.
