Death Adder of the Serpent Society has been tasked with delivering an unconscious Princess Python to the Circus of Crime for ransom. As he flies over the Bronx, his Serpent Saucer malfunctions and crashes into a large deserted building. Adder escapes from the disabled craft mere moments before it explodes, carrying his captive with him. He hides her in a safe part of the building and hails a taxi. He threatens the cabby into taking him for a ride, and the cabby keeps up some nervous patter—until he pulls a gun and shoots the serpentine criminal. Removing his rubber mask, the Scourge of the Underworld announces, "Justice is served."
The next morning at Avengers Mansion, Namor and Hercules are helping Captain America move back in. The Wasp welcomes him, and he tells her of his plans to travel around the country in a van specially customized for him by Wakandan technicians. Once they bring him up to speed on the new features, Steve Rogers heads across the country…
…where, at a nameless bar in Ohio known as a hangout for super-criminals, the villain known as the Blue Streak, in civilian guise, meets with Gary Gilbert, the former Firebrand. Gilbert tells him about the Scourge, a serial killer whose targets are costumed criminals and that he is trying to organize a network to track down and eliminate this killer. Gilbert invites Blue Streak to a meeting to be held at the bar two weeks hence. Blue Streak declines and walks out….
As Steve is tooling down the highway sometime that evening, he is passed by an extremely fast man on skates who is being pursued by a police car. He follows until he sees the police vehicle which had run off the road during the high-speed chase; he stops to help the injured officers and calls for help. When he is done assisting the rescuers, he continues on his trip. Pulling into a rest stop several miles away, he passes a man coming out of the restroom and recognizes him as the traitorous SHIELD agent Blue Streak. Steve confronts him; the Streak, fearing Steve may be the Scourge, tries to shoot him with his laser and succeeds only in destroying his own car. He ducks back into the restroom to don his armored skating outfit and emerges to find himself face-to-face with Captain America. He opens fire on Cap who disables one of the Streak’s skates with his thrown shield. The villain beats a hasty retreat down the highway and Cap pursues by motorcycle (kept in the rear of his van). A wild chase ensues along the twisting mountain roads, with Cap evading Blue Streak’s traps. Eventually Cap comes across the signs that the Blue Streak went hurling over a cliff. As he goes down into the ravine to search for him, the villain emerges from hiding up on the highway and gets away. Soon he flags down a passing truck, whose cheerful driver offers him a lift. Moments later the driver murders Blue Streak. "Justice is served."
