synopsis:
The year is 2071, a few days before Halloween. An unknown pathogen is being released in the capital city of Mars, and the government has issued a 300 million woolong reward, the largest bounty in history, for the capture of whoever is behind it. The bounty hunter crew of the spaceship Bebop; Spike, Faye, Jet, Ed and Ein, take the case with hopes of cashing in the great bounty. But the mystery surrounding the man responsible, Vincent Volaju, goes deeper than they ever imagined, and they are not the only ones hunting him. The original creators of the pathogen have dispatched an agent named Elektra to deal with Vincent, as well as take out anyone who might uncover the truth behind his murderous crusade against the Martian government. As the hunt for the man with no past and no future continues to escalate, the fate of Mars rests with the Bebop crew, a responsibility they are not so sure they can handle.
