Dead Simple

Frank operates a Motel. He dreams of opening a club where he'll sing his country songs. His wife Helen is disparaging, so when a scheming chanteuse is dumped on Frank's front door, he is bewitched. The visitor (Julie) has dispatched Helen, set in motion a con for Frank's money, called her husband to come get her, and taken Frank's army buddy into the bathtub for some fun. Frank is in over his head, just as Helen's twin sister comes for a visit & Julie's husband arrives looking for his wife. (imdb)
