Known for its Space Western theme, Trigun is about a man named "Vash the Stampede" and the two Bernardelli Insurance Company employees who follow him to minimize the damage caused by his appearance. Most of the damage attributed to Vash is caused by bounty hunters after the "60,000,000,000$$" (sixty billion "double dollars") bounty on Vash's head for the destruction of the city of July. However, he cannot remember the incident clearly due to amnesia. Throughout his travels, Vash tries to save lives using non-lethal force. He is occasionally joined by a priest, Nicholas D. Wolfwood, who is an excellent gunfighter like Vash, and is later targeted by a band of assassins, the Gung-Ho Guns, for unknown reasons.
