New Mexico Territory, August 1879. The few surviving members of a cavalry column, which has been relentlessly decimated by the Apaches, attempt to reach Fort Crain. On their way through a hostile land, the obsessive and ruthless Sergeant Vinson takes to the limit the battered will of the troopers under his command.
Unfortunately the movie Fort Massacre is not yet available on HBO Max.
