When Dr. Martin (Robert Powell) goes on a job interview at a British insane asylum, he learns that he must interview the asylum's inmates in order to be considered for the position. Dr. Rutherford (Patrick Magee), who is wheelchair-bound because of an assault by an inmate, tells Dr. Martin that he will consider him for the position if he can discover which of the inmates is Dr. Starr, a former head doctor at the asylum who suffered a nervous breakdown.
