Gunsmith Cats
Meet Rally and Mini-May, two of the most fun-loving, well-armed, bounty-hunting women in Chicago! Whether they're chasing bail jumpers or fending off the Mob, you can bet on a healthy supply of guns, bombs, car chases, and more guns!
Rally is assigned to track down a bail-jumping informant whose testimony could severely damage the Mob. Unfortunately, the Mob is onto him, and the meanest, toughest bad-girl hitwoman in the Windy City is all too willing to "ventilate" our heroines to get to the stool pigeon!
