Hellgate

This post-Civil War yarn was adapted from the story of Dr. Mudd, the physician who attended John Wilkes Booth, assassin of President Lincoln. In 1867 Kansas, veterinarian Sterling Hayden treats an injured stranger who turns out to have been a guerrilla raider--and Hayden soon finds himself serving a term in one of the world's most terrifying prisons under sadistic commandant Ward Bond.
