SynopsisThe mismatched crew of the Bebop are back, and this time they're on the silver screen. The movie takes place between (in the time period of) the Cowboy Bebop episodes 22 and 23.

Mars is under siege! Just before Halloween 2071, a terrorist bomb destroys a tanker truck on Highway One, close to a densely-populated crater city. There are casualties up to half a mile from the blast — 500 killed or injured by what appears to be a biochemical weapon. The reward for the bomber's capture is a massive 300,000,000 woolongs... and there are four humans and a dog who really need the money. Down on their luck as usual, the crew of the Bebop get on the case.
