Synopsis:
Baffled by strange disappearances of objects from a nearby town, the Challengers encounter two aliens. Rocky and Prof trail the aliens, while Ace, June, and Red fly into a strange cloud that has been near each event. Hidden inside the cloud is an floating platform controlled by alien criminals. Ace and his partners are captured by the aliens and imprisoned.

Meanwhile Rocky and Prof are attacked by a metallic beast. The two aliens come to the rescue and explain that they are the scientists who created the floating platform. However, it was taken over by Zog, a criminal, and his men.

Rocky and Prof stow away aboard an aircraft flown by the alien scientists to the platform. The scientists are captured by Zog, but the Challs free their captured partners. By creating a distraction, the Challs give the scientists time to use a secret device which defeats the criminals. They then return to their home planet with their prisoners.
