Once they are married, a business partner of Johnnie's turns up dead, and Lina begins to wonder how well she really knows her husband.
Johnnie Aysgarth (Cary Grant) is a charming ne'er-do-well who wins the affection of Lina McLaidlaw (Joan Fontaine), a wealthy woman whose father is suspicious of Johnnie's intentions. Once they are married, a business partner of Johnnie's turns up dead, and Lina begins to wonder how well she really knows her husband. This is a classic example of Hitchcock playing the hits and letting his stars shine to create a wonderfully entertaining film.
