Welcome to 1876 America, a place bursting with gunslingers, outlaws, and garou--better known as werewolves. And where there are garou, there're hunters: the one and only Calamity Jane, to be precise, along with her fellow stars of Wild Bill's Traveling Show, Annie Oakley and Frank "the Pistol Prince" Butler. After a garou hunt goes south and Jane finds a suspicious-like bite on her arm, she turns tail for Deadwood, where there's talk of a garou cure.
