Wealthy, sheltered Lina McLaidlaw is swept off her feet by charming ne'er-do-well Johnnie Aysgarth. Though warned that Johnnie is little more than a fortune hunter, Lina marries him anyway and remains loyal to her irresponsible husband as he plows his way from one disreputable business scheme to another. Gradually Lina comes to the conclusion that Johnnie intends to kill her in order to collect her inheritance. The suspicion seems confirmed when Johnnie's business partner dies under mysterious circumstances.
