Lucky

Ben Keller is sort of a bumbler who carries a torch for Lucy, a co-worker he's known since childhood. She's indifferent until he wins $36 million in the Iowa lottery; trouble is, he murdered the young woman who bought the ticket (it's not his first murder), but the mercenary Lucy doesn't discover Ben's secret until their honeymoon. She figures out that he murders women who look like her, so she's probably safe: she'd like to wait for the next lottery check to come in the mail, then run away. Ben knows she knows and wants her to love him anyway. With a police detective sniffing around and Ben's protective mother watching things carefully, can Lucy make a great escape?
