Utilizing a number of bizarre weapons, a gang of criminals pulls several daring robberies. The Blackhawks trail one of the gang’s machine only to see it disappear from sight along with three of their teammates. Blackhawk puts together some clues to trace the gang to Island X.

The team arrives to discover a wrecked spacecraft from which the weapons have come. The crooks use more alien devices against the Blackhawks, but they are done in by one of their own inventions controlled by Chuck, who escaped from a cell using his diamond ring.
