Another Indian treaty is broken and the angry Apaches, led by Hollywood/exploitation veteran Ray Danton, are massacring any blue-coat they come across. Meanwhile, a civilian Army scout is mauled by a bear and left for dead by his troop, much like Richard Harris in Man In The Wilderness. (a much better film)
The enjoyment (or non-enjoyment) of Apache Blood is entirely dependent on one's tolerance for no-budget drive-in schlock.
The film is told with minimal dialog and almost entirely in pictures with familiar library music blaring away, keeping it from being totally boring but also hampering the story a bit as well.
After a lousy ending, the final eight or so minutes is a complete waste of time with a long slow-motion sequence recounting all the movie's violent moments, as well as an artist's rendering of Danton as the Apache explored at length by the camera!
