Synopsis:
The Blackhawks investigate the disappearance of a missing mountain expedition only to uncover a hidden alien city. A gang has taken control of the city and put the expedition to work as slave labor. The Blackhawks are captured and put to work as well.

Blackhawk sneaks away and learns the origins of the alien technology. He plans to grab the control unit of the multi-machine that the crooks are using. The team is successful, but they don’t need to confront the gang at all since the alien equipment disintegrates once it leaves the mountain. The gang is defeated.
