Currently, there are no confirmed plot details to speak of for the upcoming "Sin City" TV series. However, with the show adapting elements of Frank Miller's graphic novels of the same name, it stands to reason that it will likely take place in the fictional Basin City. That said, some of the earliest reports, including one from Deadline, have indicated that the first incarnations of the series were planning to move away from established characters and explore new avenues of the franchise not specifically seen in the books or films.
Some things have changed since the time "Sin City" was first announced, however. With both Miller and Rodriguez possibly working on the series in some capacity, it's possible (though unconfirmed) that it could return to some of the seeds planted in segments like "The Big Fat Kill" and "The Yellow Bastard." Whether that means we will see a show that tells stories before, during, or after those sections of the "Sin City" timeline remains to be seen.
