The Immortal - Season 1 Episode 14 Sanctuary

Ben's latest escape from Fletcher takes him onto an Indian reservation. His transportation is not very reliable -- a dune buggy he almost finished repairing before fleeing in it. Three young Indians on horseback offer to help Ben -- for money. Ben falls down an embankment and is thought dead by the youths, but the tribal elder thinks otherwise and orders them to bring Ben back. Ben recovers and sets about trying to repair the dune buggy, having to improvise because there are no mechanic tools. Fletcher's men spot the dune buggy's tracks and move in. Firing tear gas into the compound, they grab Ben and head away from the reservation with the youths in pursuit on horseback.
