On the eve of Halloween in 2071, an amazing crime suddenly occurred in the big cities on Mars. A tanker exploded on the highway. People at the scene of the accident fell ill for unknown reasons, with more than 400 dead and injured. Such a large-scale incident seems to have been caused by biological weapons of unknown origin. To this end, the Martian government issued a 300 million yuan reward for terrorists. Faye, who witnessed the incident, acted alone in an attempt to monopolize the reward, and Eddard used hacking technology to find clues and act with everyone on the Bebop. The group of four men and one dog set out again, but they did not know that the price of 300 million yuan was to fight against unprecedented powerful criminals.
