Colonel Adam Cook crash-lands on a strange planet with gravity and atmospheric conditions similar to those of his home world. Most of his equipment is destroyed in the crash and cannot be repaired due to a broken right arm and lack of resources. He contacts his home base, but they have little encouragement for him; there is no replacement spacecraft to rescue him, and his home planet may be at war in a matter of hours. They promise to send instructions on how to repair his ship. From base, General Larrabee reports that the enemy attacked and destroyed their entire coast in 12 minutes, after which they retaliated. Those at base will have to move soon, meaning Cook will not have anyone to contact. Cook leaves his ship at night and finds drawn patterns in the dirt. While looking for the source, he is hit by a rock from an unseen source, and knocked unconscious. During this time, General Larrabee sends his last transmission to Cook reporting that the radiation from the attacks will kill any remaining survivors, so Cook can expect no rescue. Upon regaining consciousness, Cook returns to his ship and is startled by a noise coming from a closet. Cook leaves the ship as a gesture showing that he means the alien no harm. A human-like female emerges from his ship. Not knowing each other's languages, they communicate through sketches in the sand and pantomime. He learns that she is also stranded; her planet left its orbit and she is its sole survivor. Her name is Norda. As they ready to look for food, Cook picks up a stick, which Norda interprets as a threat. She scratches his face and runs. Soon after, Norda returns and expresses remorse for her actions, which Cook happily forgives. They find a more fertile area, which Cook likens to a "garden." He fully introduces himself as "Adam Cook" and Norda gives her full name as "Eve Norda". Adam and Eve begin a new life on this planet she calls "Earth." At this point she offers him a "seppla". As they venture further, Rod Serling narrates that he presumes the place they are heading to is Eden.
