The beginning of the seventh story arc in the long-running JoJo's Bizarre Adventure series.
It’s 1890, in America, the Steel Ball Run — the first horse racing championship across the North American continent — was about to begin. Johnny Joestar, once being hailed as a genius jockey, is now paralysed and lost in despair. Il trouve de l'espoir dans les mystérieux phénomènes provoqués par Gyro Zeppeli, un hors-la-loi visant à remporter la course, et décide de participer aux 4 000 milles d'une aventure exténuante.
