While traveling to the countryside of England by train, the repressed, shy Lina McLaidlaw meets reckless playboy Johnnie Aysgarth when he crashes her first-class cabin with a third-class ticket. When they meet again, Johnnie overhears a conversation of her father about her heritage and courts her, and she immediately falls in love with him. They get married and when they return from their fancy honeymoon, Lina discovers that Johnnie is a broke gambler who borrows money from his friends to live in a high standard. Then she finds out that he is also a liar, and after receiving his old friend and partner in a real-estate business, Beaky, in their home, Lina believes that Johnnie intends to kill Beaky. However, they decide to travel to Paris to dissolve their partnership. When two detectives come to their house to investigate Beaky's mysterious death in Paris, Lina believes Johnnie is the murderer, and she will be his next victim.—Claudio Carvalho, Rio de Janeiro, Brazil
