Plunderers of Painted Flats (movie, 1959)

To scare the squatters from the cattle country he claims as his own, rancher Ed Sampson orders the Martin farm house burned. Galt Martin is killed, and his eldest son, Joe, is pistol-whipped. Timmy Martin sees the killer, Cass Becker and points him out when he and Joe are in Painted Flats. Cass forces Joe to put on a gun but Ned East, a retired gunfighter, saves the inexperienced Joe by forcing Cass to draw on him, and Ned is the winner.
