Shock Treatment (1964)

Former psychiatric patient Martin Ashley is declared sane and released from an insane asylum. He works as gardener and chauffeur for a wealthy woman in Beverly Hills. Tired of being verbally abused, he kills her and surrenders to police. During the court proceedings, it is revealed that Ashley burned one million dollars of his employer's money because he considered money to be the source of all evils. The court deems him insane and returns him to his former institution in the care of his old psychiatrist, Dr. Edwina Beighley. The estate's executor, Harley Manning, believes that Ashley is faking insanity and has murdered the old lady for her money. Manning believes the money wasn't burned but stashed away somewhere. He hires actor Dale Nelson to feign insanity to be sent for psychiatric evaluation at the same institution where Martin Ashley is. For a fee, Dale Nelson agrees. He commits a misdemeanor and the court sends him for a 30-day evaluation at the psychiatric institution. Once inside, he is to befriend Martin Ashley and find out where the million dollars is stashed. However, Dale Nelson and Harley Manning aren't the only ones interested in finding the money. Starved of research grants and funds, unscrupulous psychiatrist Dr. Edwina Beighley also wants to find out whether her patient, Martin Ashley, has really burned the million dollars or has stashed away someplace. She figures she can use hypnosis on Ashley to wrest the information out of him. Dr. Beighley and amateur sleuth Dale Nelson are on a colliding course, but Beighley has a syringe full of nasty experimental drugs in her hand and Nelson is strapped to a bed in the electroshock therapy room. Now he needs a fast miracle to get him out of this mess.
