Expert gunsmith Rally Vincent (slender, curvy, all-business brunette packin' heat) and her maniac side-kick Minnie May Hopkins (short, cute, dizzy blonde explosives nut) are happily running a gun shop and a bounty hunting operation in Chicago, when pony-tailed and hunky ATF Agent Bill Collins saunters into their lives. With a little coercion, Bill leads the Gunsmith Cats on a bullet-riddled mission to bust a ring of gunrunners by setting up a sting on smuggling under-boss Jonathan Washington.
