However, the local thugs turn out to be the smallest of Hall's problems. A task force of hostile alien invaders are preparing to enslave mankind with the use of hypno-wave devices and advanced androids; already they control the local authorities and military installations. Charlie immediately senses the true nature of these individuals, however, and after much persuasion convinces his big friend to look into the matter. But this arouses the suspicion of the alien leader (Claudio Undali); he has Hall arrested for snooping into matters of national security and Charlie kidnapped.
