The private war between the Knight Sabers and GENOM heats up when GENOM recovers the "Black Box" that controls the U.S.S.D. satellite weapons system from the wreckage of Aqua City. Mason, the sinister GENOM executive in charge of the project, incorporates the Black Box into his pet project, the SuperBoomer android, and sets his Boomer assassins on the trail of anyone who stands in his way--including a friend of one of the Knight Sabers.
