Phobia (1980)

What happens when your Psychiatrist goes out of his mind?

Dr. Ross uses a radical branch of psychology in which those under his care are forced to confront their phobias head-on, and which include agoraphobia and an aversion to snakes. Though his technique initially yields positive results, his practice begins to fall apart when one patient is murdered. This motivates the dedicated psychologist to plumb deeper into his clients' lives...and his own fears. Soon, everyone around him is exhibiting strange behavior--or is the doctor the one who's really in trouble?
