The Trackers

A rancher returns to his home to find his son dead and his daughter missing. Before dying, his son tells him that they were attacked by troopers. He then organizes a posse and sends for his friend a Marshall, who's the best tracker there is. But his friend sends his Deputy and protege, a Black man. And the first thing he reveals is that his daughter was not taken by troopers but by Indians, but the man steadfastly maintains that he believes it was a trooper. Eventually he proves them wrong. And they go on with the Deputy leading the way.
