After delivering a herd of cattle to the town of Sand Dust, Joe and Hoss Cartwright, together with ranchhand Candy and local girl Valerie Townsend (Davey Davidson), are eyewitness to a fatal shooting. When the brothers of accused killer Billy Slader (Michael Blodgett) threaten to permanently silence all four witnesses, Sheriff Dunkel (Robert McQueeney) puts them under protective custody, leading to several unexpected plot complications. Frederick Down and Bill Fletcher are cast as the homicidal Slader siblings, while Russ Conway is seen as Judge Wheeler. Written by Eric Norden, "False Witness" first aired October 22, 1967. ~ Hal Erickson, Rovi
