Set in present day Chicago, Gunsmith Cats tells the story of two bounty hunters/gunshop owners named Rally Vincent and May Hopkins. Rally, known for her skills in handling guns has also made a name for herself by running a quality gunshop and for also bringing in criminals in her part time job as a bounty hunter, a job she takes very seriously. Her partner, May Hopkins, has an amazing talent for handling explosives regularly carrying large numbers of them and their accessories in her clothing.
Together, they are the Gunsmith Cats and getting in their way will only serve to get your butt kicked. Working with the ATF to bring down an gun smuggling ring, the cats quickly find themselves caught up in a much larger, more complex situation than they anticipated. With a lethal Russian named Radinov, a trained KJB member out to kill them and a dorky ATF agent named Bill Collins along with a timid comptuer geek as their only allies, the Cats definitely have their hands full. First working to infiltrate the gun smuggling operation, Rally is eventually able to help Collins get to the heart of the illegal organization and put a stop to their activities once and for all.
