In 2071, crimes were rampant everywhere in the universe, and the police could not cope with it, so they introduced a bounty system to encourage civilians to hunt down criminals. The extraordinary Spike and former policeman Jeter formed a bounty hunter partner, and rode around on the spaceship "BEBOP". They have caught criminals offering millions of rewards, but they have to deal with various claims because of Spike's behavior, so they have been in poverty almost all the time. During the journey, the beauty Fei, who loves money like her life, the talented hacker girl Ed, and a lazy-looking high-smart dog also became members of "BEBOP".
A big explosion of a fuel transport vehicle occurred in the Martian city of Alba. People around the scene of the incident have successively died of strange diseases, and the number of victims has exceeded 400. The police believed that this was a terrorist act involving the use of biological and chemical weapons, with an unprecedentedly high bounty of 300 million. It happened that Fei, who was tracking the credit card embezzlement incident, accidentally took a video in which the man with the tattoo on his arm was the culprit in this vicious incident.
In order to win a huge bounty, the members of "BEBOP" launched an action. Spike will have a life-and-death duel with the immortal Vincent.
