When a man dies of a heart attack, a stage and radio mentalist believes he has willed him to die because he was angry with the man. Riddled with guilt, the mentalist cancels further shows, breaks off his engagement to his female partner, who can read minds while in a hypnotic trance, and takes refuge in the eerie wax-museum-cum-home of another woman friend.

The show is about doctors Marcus Welby, a general practitioner and Steven Kiley, Welby's young assistant. The two try to treat people as individuals in an age of specialized medicine and uncaring doctors.
