When a dangerous patient is released from the State mental hospital, a nurse contacts his one-time psychiatrist, Dr. Maxwell Stoddard and urges him to call the police. The released patient, a man named Litton, had been in the hospital for over 15 years and was known as the Mole for his penchant to kill his victims in the dark. Working with Detective Sergeant Jim Willis, Dr. Stoddard tracks the patient to a construction site where they have a fateful encounter.
