When the SWAT Kats’ arch-nemesis Dark Kat steals the material for a homemade nuclear bomb to destroy Megakat City, neither the SWAT Kats nor the Enforcers can break through his defensive forcefield. Commander Feral tries to sneak aboard Dark Kat’s ship to defeat Dark Kat and retrieve the stolen parts, but is quickly subdued. The ambitious Lt. Steel (Hal Rayle), Feral’s slimy second-in-command, would rather advance in his career than rescue his boss, so it is up to the SWAT Kats to save both Feral and Megakat City. In the middle of the episode, there is a flashback revealing that Jake and Chance used to be members of the Enforcers, and while pursuing Dark Kat the first time with Commander Feral, cause considerable damage to Enforcer Headquarters. They are subsequently removed from the Enforcers and are forced to take a job at the Megakat City Salvage Yard to pay for the damage. There they use old airplane and engine parts to create the Turbokat and become the SWAT Kats.
