Synopsis:
The Challengers track down Albom, a thief who has stolen a machine capable of causing great disasters. Albom is protected by an alien metal creature named Halanka. The Challs are forced to retreat and return with an electro-magnet to deal with the large alien.

When they return, they find two sets of tracks. Ace and Rocky follow the first set which leads them to Albom and Halanka. The magnet works at first at immobilizing the giant, but Albom causes him to super-heat which melts the Challs weapon and jeep.

Prof and Red follow the second set of tracks and meet Thark, an alien lawman who is trying to recapture Halanka. The Challs and Thark team up to defeat the villains and destroy the dangerous machine Albom has stolen. Thark then returns to his world with Halanka.
