When a Woman Meddles(1957)

Original title: Quand la femme s'en mêle

French film favorite Edwige Feuillere plays a high-class gangster's moll named Maine. When Maine's first husband and daughter pay a visit, it's an awkward time for our heroine and her current amour, gang boss Godot (Jean Servais). In addition to fielding a lot of embarrassing questions, Godot also has to deal with a pesky turf war with a rival mobster. Not that the ex-husband is a paragon of virtue: he's busy trying to get even with a crooked business associate.
