Set in the nineteen-thirties, From Within weaves an epistolary tale of terror and loss through the letters and journals of those who survived... and some who did not. Season one follows Sheriff Flynn, Dr. Cooper, and Hattie Ogle as they and their fellow residents of the township of Blightwood endure a threat beyond the reach of their comprehension. Something lurks in the hills and coves that surround the isolated mountain community. Something violent, uncanny, and hungry.
