New-Port City has a problem with crime, and in order to combat this, the mayor orders the creation of a new police unit: THE TANK POLICE! Trouble ensues when the young and feisty recruit Leona is transferred in from the motorcycle-division, and has a little problem getting used to the tanks, and accidentally destroys the personal tank of the units commander, Lt. Britain. Threatened with re-assignment, Leona builds a new smaller tank out of spare parts of Lt. Britain’s old tank. The new tank, christened Bonaparte, is finished just in time to stop Crime-Lord Buaku and his henchwomen, Annapuna and Unipima, from stealing urine from people who are un-effected by the poison cloud that hangs over the entire planet. Finally accepted into the Tank Police, Leona ends up causing as much, if not more, trouble then the others ever did.
