Stardate 3715.0: An Enterprise landing party beams down to an edenic planet, where Kirk discovers that the people living there are still primitive, all progress held in check by an enormous ancient computer known as Vaal, which also demands sacrifices of food by the natives. Vaal detects the Enterprise in orbit and begins to drain it of its power, and Kirk realizes that he will have to destroy Vaal to save the Enterprise, but the surface dwellers’ lifestyles will be changed forever if Vaal is removed.
