Intergalactic mercenaries Gizmo (the robot) and Fluffy (the big dog-like alien) travel through space traffic to get to their new assignment, "six weeks of light but exciting duty on a tropical paradise planet." But once they arrive, our heroes discover that the world is anything but paradise. Unfortunately the duped duo can't leave early as their ship has been impounded until their tour of duty is complete. As the guys transverse the rain-soaked jungles with their fellow "vacationers", they're attacked by a giant monster that kills several soldiers before the others scatter in effort to save their lives.
