The Megakat Metallurgical Company has some problems: several of their miners have gone missing deep in the company's agracite mines. The Enforcers are called in to investigate by Taylor, the company's mining foreman, with Ann Gora tagging along incognito as a miner. When she too disappears, it's up to the Swat Kats, with help from Lt. Felina Feral, to enter the mines and find her. They soon discover the root of the problem, too - a horde of giant scorpions mutated by toxic waste that was illegally dumped by Megakat Metallurgical's president, Tiger Conklin.
