The moon passes an asteroid which shows signs of something unusual beneath its surface. Using explosive charges, an expedition led by Koenig and Professor Bergman unearths a door of artificial origins. An attempt to open a door further inside the underground installation results in a huge explosion, and while the second door opens, someone who was standing behind it is critically injured. Koenig and his landing party return the humanoid to Moonbase Alpha, where he dies on the operating table. And yet, when Dr. Russell prepares to conduct an autopsy, she finds that the humanoid is unharmed – in fact, his body is regenerating. Before long, the fully-restored alien visitor is on his own two feet again, exploring the Moonbase, despite security’s best efforts to restrain him. Though he expresses his gratitude to Koenig for freeing him from the asteroid, the entity known as Balor soon all but takes over Moonbase Alpha in a display of power and pure evil.
