Private nurse Ange (the stunningly beautiful Agnès Lemercier) seems to make a good living eliminating filthy rich, disgruntled old men at the request of their second and third wives, invariably much younger. After her latest “success,” she heads to the French countryside to care for millionaire Gilbert Servien, who is making life miserable for his entire family, especially his nymphomaniac wife Carole (impressively played by the sad Marie-Dominique Cabanne) and his estranged bisexual son (the underrated Joël Charvier in a blistering performance). Meanwhile, Ange smothers the old man with kindness, taking the time to seduce each family member separately in a series of highly creative encounters.
This debut work by the extraordinary adult filmmaker Gérard Kikoïne remains one of his finest achievements. Revered as a director of vision and sophistication far beyond the adult film critics' circle of the early 1980s, he later chose to repudiate the "discredited" genre that made him famous, in favor of B-movie obscurity. The script for "Entrechattes" (renamed "L'infirmière" for the DVD release) is unusually incisive, and the acting is far better than average, creating a contradictory effect that draws the viewer into an oppressive and unhealthy hothouse atmosphere.
