Team Guppy are a group of what are known as "Crackers" -- skilled bounty hunters who make a living fighting against space pirates under contract from the Galactic Police. Team Guppy haven't been around long, and aren't particularly famous, so they don't get a whole lot of work. One day, they get a request from the Galactic Police to respond to a pirate attack on Jack Station, and they jump at the chance.
