When a psychologically disturbed member of the staff of the Tantalus penal colony, Dr. Marcus Van Gelder, manages to escape onto the Enterprise, Captain Kirk and Dr. Helen Noel beam down to the planet to see exactly what is going on there. The head of the prison is a renowned penologist, Dr. Tristan Adams, greatly admired for the advances he has made in treating criminals. While Dr. Noel can find no fault with Dr. Adams or the practices at the colony, Kirk isn't so sure. Mr. Spock must use the Vulcan mind meld on Van Gelder to get to the truth. Written by

The "Vulcan mind meld", introduced in this episode, was originally a way of working around a warning from NBC's "Standards and Practices" department. In an earlier draft of the script, the plan had been to have Spock hypnotize Van Gelder, but writers were told that they must have hypnotism performed "by DOCTOR McCoy rather than MISTER Spock" unless they could establish that Spock had been specially trained to do this.
