Summary
It has been 49 years after Jonathan Joestar's death, and a much older looking Speedwagon and Straizo travel to Mexico to investigate a mysterious underground cavern. There they find it filled with similar Stone Masks to the one that was destroyed many years ago, as well a body integrated into a stone column.

Meanwhile in New York, a peculiar tourist gets his wallet stolen by Smokey, a local pickpocket. However, he then saves that same pickpocket from two violent and corrupt policemen by using the Ripple. This man is Joseph Joestar, the grandson of Jonathan Joestar. Joseph has just arrived to the United States with his grandmother Erina, who has been taking care of him since his father and mother died.

Back in Mexico, Speedwagon is betrayed by Straizo. Straizo has come to envy the youth that the Stone Mask had granted Dio and dons one himself, to Speedwagon's horror.

JoJo, Erina, and Smokey all go to a restaurant, only for a mafia henchman to insult Smokey. Furious, Joseph takes the time to put back the man in his place. During the scuffle, Joseph amply demonstrates his talent at reading and outsmarting his opponents. However, a mafia acquaintance of Speedwagon's informs them that Speedwagon has been murdered by Straizo. Later that night, JoJo is confronted outside a cafe by Straizo, who had regained his youth as a Vampire.
