Double indemnity

A calculating wife encourages her wealthy husband to sign a double indemnity policy proposed by smitten insurance agent Walter Neff. As the would-be lovers plot the unsuspecting husband's murder, they are pursued by a suspicious claims manager.

In 1938, Walter Neff, a successful insurance salesman, strangles his wife Phyllis Dietrichson. Neff plots to make the murder of her husband appear to be an accidental fall from a train that will trigger the "double indemnity" clause and pay out twice the policy's face value. The story, told primarily in flashback, ensues. The victim's daughter, Lola, comes to him convinced that stepmother is behind her father's death.
