Vittorio De Sica directs this Italian romantic comedy drama starring Sophia Loren and Marcello Mastroianni. Filumena (Loren) lives a comfortable life as the mistress of successful businessman Domenico (Mastroianni), whom she first met aged 17 when she was working in a brothel. However, when Domenico becomes engaged to another woman Filumena feigns illness. Filumena then, pretending to be on her deathbed, asks Domenico to marry her and he agrees only because he believes she has days left to live. Once Filumena reveals her deception she also opens up about having three sons and uses them as a ruse to keep Domenico interested in her.
