Vash the Stampede carries a sixty-billion-dollar bounty and a reputation as the Humanoid Typhoon, a monster said to erase entire towns wherever he goes. The truth is much stranger: Vash is a pacifist who hates killing, loves doughnuts, and often leaves destruction behind mainly because he is trying to save everyone at once.

Insurance agents Meryl Stryfe and Milly Thompson follow him across the desert planet Gunsmoke to reduce the damage surrounding his adventures, but their assignment becomes far more dangerous when assassins begin targeting Vash specifically to break his principles. Beneath his ridiculous behavior lies a long history of loss and an enemy who understands exactly how to force him into impossible choices between protecting innocent people and keeping his vow never to take a life.
