Shock Treatment

Losing her young lover makes Helene (Annie Giradot) feel old, so she heads off to a health resort she has heard does wonders for people. The treatments really do make her and the other guests feel better, and for a while that is enough. She cavorts nude on the beach with the head of the clinic (Alain Delon), made unself-conscious by an excess of vitality. However, she stumbles upon the clinic's dark secret: the clients' rejuvenation comes at the expense of Portuguese youths, who arrive at the clinic to work in the gardens and are never seen again.
