While investigating the sinking of a German ship off the coast of England, the Red Torpedo II in his similarly named submarine encounters several robotic crabs created by the Jester II. Capturing one of the crabs, he realizes it was meant to sabotage oceangoing vessels.
Meanwhile, the Blue Tracer secretly delivers Happy Terrill (the Ray) to Occupied England on a mission to infiltrate the S.S. Ubermenschen by replacing that team's Ray II with the real one. After he arrives, Terrill learns that the Ray II has already been captured by the English Resistance figure called 711 (Willie Schultz).
Terrill successfully passes himself off as the Ray II of the S.S. Ubermenschen with the team, and the Red Torpedo II leads the team on a mission to track down the Jester II. Unfortunately, the S.S. Ubermenschen are instead led into a trap by the Jester II and only barely manage to escape.
Meanwhile, in Occupied California, Quicksilver II damages Los Angeles City Hall, making it unusable in its current function as Occupation headquarters. The Manhunter II, former leader of the S.S. Ubermenschen, demands Quicksilver II to give himself up, or he will begin killing people. Instead, Quicksilver II attacks Manhunter II, damaging his legs and forcing him to retreat.
After his creator Dr. Joseph Mengele supplies him with a formula, the Manhunter II gains new powers, including a limited self-healing ability, flight, and the ability to shoot heat rays from his eyes.
Patrick Ito begins sabotaging the coastal batteries in Los Angeles in preparation for an American invasion of Southern California.

The Blue Tracer secretly delivers the unconscious body of the Manhunter II to Project M in Nevada.
