Girls, guns and grenades! Meet Rally Vincent and Minnie May. By day, they work at the Chicago gun shop that they own. By night (or holidays or week-ends), they moonlight as a pair of bounty hunters called the Gunsmith Cats. Rally is an expert at firearms, being able to judge the condition of a gun at a glance, and an expert marksman. Minnie is younger and less disciplined; and has an obsession with explosives. Lots of explosives. Especially big ones. Together, they form an unbeatable team; much to the consternation of the local ATF bureau. Set in the city of Chicago, Rally and Minnie always seem to be in the midst of gunfights, car chases and general mayhem.
