In the ravaged near-future, a savage motorcycle gang rules the road. Terrorizing innocent civilians while tearing up the streets, the ruthless gang laughs in the face of a police force hell-bent on stopping them.

At Melbourne's Russell Street Police Headquarters, Sgt. "Bluey" Hills, unable to work within the existing police squads, oversees Department B. They're assigned cases other departments could not readily solve by conventional means, with Hills applying his unconventional methods to bring about their resolution. Bluey's investigations are supported by newly assigned Gary Dawson, long-time cohort Monica Rourke, and undercover officer Reg Truscott, who spends his time ostensibly working as a small-time burglar, and supplying Bluey with information on the activities of local criminals.
