Plot
Twenty years prior to the events of Trigun, the outlaw Gasback and his gang rob a bank. The other henchmen betray him and escape with the money, and their leader Cain shoots Gasback and leaves him to be caught by the police. Vash the Stampede intervenes to stop Gasback from killing any of the others; Gasback escapes capture and continues his life of crime.
In the present, Cain has become the mayor of Macca City, using his share of the robbery money to upgrade its power plant and construct a huge bronze statue in his likeness. One of the other henchmen, Dorino, has been forced to take shelter with Cain after Gasback destroyed his business. Cain applies to the Bernardelli Insurance Society for a policy on the statue, prompting Meryl Stryfe and Milly Thompson to travel to Macca City in an attempt to keep it safe.
