After her twin sister is murdered in a dressing room standoff, Gretchen Tanner seeks revenge by murdering the parasite who put her sister in an early grave. Unfortunately for her, she finds revenge brings more trouble than it’s worth. Gretchen’s accomplice in murder discovers her darkest secrets and uses them to force her into acting as his delivery girl, delivering packages with undetermined nefarious contents. Much to her dismay, he arrives at the funeral home in an official FBI capacity, asking questions about the murder. To make matters worse, he shows up as her Criminology professor. Each man professes a separate identity and a severe aversion to the others while flirting with her. Her only conclusion is that he suffers from Multiple Personality Disorder, leading her to wonder: if a woman dates a man with multiple personalities, can she still call herself a one-man woman?
