In Florida, 2011, Jolyne Kuujou sits in a jail cell like her father Joutarou once did; yet this situation is not of her own choice. Framed for a crime she didn’t commit, and manipulated into serving a longer sentence, Jolyne is ready to resign to a dire fate as a prisoner of Green Dolphin Street Jail. Though all hope seems lost, a gift from Joutarou ends up awakening her latent abilities, manifesting into her Stand, Stone Free. Now armed with the power to change her fate, Jolyne sets out to find an escape from the stone ocean that holds her.

However, she soon discovers that her incarceration is merely a small part of a grand plot: one that not only takes aim at her family, but has additional far-reaching consequences. What's more, the mastermind is lurking within the very same prison, and is under the protection of a lineup of menacing Stand users. Finding unlikely allies to help her cause, Jolyne sets course to stop their plot, clear her name, and take back her life.
