Spike and Jet are bounty hunters, they watch the (Big Round-up show?) and go hunt the people who have a good bounty. Along the way they pick up a few other characters and pets.. Anyway the whole series is basically about them hunting bounties, with some emotional things thrown in at times. Basically toward the end of the series they end up getting broken up, Faye and Edward (Faye they had caught for a bounty but ended up teaming together, Edward who asked to come along with the crew and forced them to pick her up) went off to find where they belong.. also a smart dog they picked up (Ein) went with Ed. Jet was left on their ship, Spike went to settle an old score with a gang he used to be in.. the ending was terrible though =(, but I won't give it away. There was also a movie, but I haven't seen it.
