In order to make important repairs, the Jupiter 2 sets down on an alien planet. As they do so, they mistakenly drag a nearby space capsule down to the planet with them. This act catches the attention of Zeta Galaxy Law Enforcement Bureau because the capsule contains something very dangerous. During the night, the Robot sneaks out of the ship and goes to a cave. Within the cave is a female robot, the fallen capsule’s passenger. She is evil, but the Robot is drawn to her all the same. She convinces him to reassemble her and to help her regain her strength.
