Love in Strange Places (1976)

Sinopsis

When Nurse Blue gets a job at the Hospital for the Sexually Insane, she knows she'll have her work cut out for her - after all, a ward full of orgasm addicts is enough to keep anyone's hands full. But when she arrives at the hospital the situation is crazier than she expected. The two directors of the hospital, Dr. Hook (John Holmes) and Dr. Fraud, practice a rather unusual form of therapy wherein sex is the key for recovery. Soon, Nurse Blue discovers that the hospital is filled with hysterical patients who believe they're doctors and nurses.
