Cowboy Bebop: The Movie (2001)

Spike Spiegel and his gang of roguish but lovable intergalactic bounty hunters are back —and this time they're on the hunt for one of the deadliest terrorists in human history. A pandemic of a deadly virus has broken out in Mars, and a 300 million woo-long reward has been offered for the capture of the terrorist behind the outbreak. But there are other bounty hunters on the trail, and the motives of their primary suspect aren't as apparent as they might initially seem. The creators of the virus have their own agenda that goes beyond a simple attack on a colony.
