Le Couteau dans la plaie (1962)

Immediately after Lisa declares that she is leaving her immature, abusive, but easy-going husband Robert, he is reported dead in a plane crash. Secretly still alive, he convinces her to collect his life insurance, although she knows that it's a bad idea. Lisa must contend with the complications of the scheme, which involve an aggressive suitor, Robert's jealousy, and her own guilt.
