Robert E. O. Speedwagon has become a wealthy oil tycoon. In 1938, his expedition crew uncovers a tomb in Mexico filled with Stone Masks and a petrified yet living body embedded in a stone pillar. Straizo, obsessed with immortality, kills Speedwagon's archaeological team and uses some of the wounded Speedwagon's blood to activate a Stone Mask. Joseph Joestar, Jonathan and Erina's grandson, has recently moved to New York from England with Erina. Joseph uses his Hamon to save a young pickpocket named Smokey Brown from some crooked cops. Smokey is then taken in by Erina. Joseph is later confronted by a rejuvenated Straizo who has come to kill him before his abilities become more powerful. Joseph makes the first move with a surprise Tommy gun attack after being informed of Speedwagon's death prior to this.
