 While out foraging for food, Barry collapses in pain and it soon becomes apparent that he is suffering from appendicitis. It is then decided that Betty, who has nurses training, will perform the operation. Steve and Mark then go to a local hospital to get the supplies needed for the operation. However, they soon encounter sympathetic Doctor Brulle, who decides to help the castaways and supply them with a medical kit that was on another ship that crashed on the planet on one condition; that Fitzhugh helps to translate a medical encyclopedia that is written in German. After the terms are agreed upon, the doctor supplies them with the medical kit and the rest of the castaways transport Barry to a clearing in the forest for the operation. Unfortunately, a janitor who felt the doctor was treating him badly, follows the doctor and reports him to the police.
