Shock Treatment

Hélène (Annie Girardot) is a worn-out Parisian who goes to visit her friend Gérôme Savignat (Robert Hirsch) at a remote rejuvenation clinic run by Dr. Devilers (Alain Delon) and his partner Dr. Bernard (Michel Duchaussoy). She arrives as a guest, and then a series of deaths gives her reason to look at the place more closely. Alain Jessua keeps her inside the clinic's walls, where every question she asks puts her own safety on the line.
