Directed by Edmond T. Gréville

Film Synopsis

Norma O'Brien, an aspiring young actress, and her lover, Dominique, are looking for an opportunity to brighten their future prospects.  To that end, they scan the personal ads hoping that fate and cunning will secure for them an easy escape from the present humdrum existence.  In Paul Dutraz, a man recently returned from Africa, they appear to have hit upon the perfect victim.  He is looking for a wife, a mature woman whose experience and dependability will make up for her lack of youth.  Norma wastes no time replying to Dutraz's ad, and being an actress she has no difficulty making herself up to resemble a woman of fifty years.  When they meet, Norma would seem to be exactly the woman Dutraz had in mind, but insists that theirs will be a marriage of convenience, since they will have separate rooms.  Norma confides in her prospective husband that she already has a son, who is none other than Dominique.  The pretext of an injured leg is enough to allow the latter to be accepted by Dutraz as a guest in his house.  It isn't long before Dutraz begins to suspect the true nature of the relationship between Norma and Dominique, but whilst he has a tender regard for Norma he feels that he must arrange a merciless trap...
