Roy has taken on the job of protecting murder witness King Keady from gangster Max Marcella. Keady saw Marcella kill a man and is now in danger of being murdered himself. Keady is a nasty tempered middleweight boxer training for a championship fight. His manager, Willie Winder, unwittingly sends King's wife some money and puts the return address on the envelope. Now Keady's young son has run away from home to find his father, even though dad thinks of his awkward son as a sissy and wants nothing to do with him. Marcella trails the boy to Mineral City. Now Roy has to try to protect King and also bring King and his boy back together. Early in the episode, watch for the scene where the bus arrives with young Keady getting off. That's Cactus Mack playing the bus driver. He has the line, "here's the boy's bag, Roy." Cactus' Mack's real name was Curtis McPeters. He was a cousin to both Glenn Strange and Rex Allen. In the 1930's, he and Glenn formed a band, The O Bar O Cowboys. When Glenn and Cactus decided to leave the band and try acting in cowboy movies, they turned it over to the youngest band member, Leonard Slye. That, of course, was Roy Rogers and the band eventually became The Sons of the Pioneers. This is a good entertaining episode that can be enjoyed by kids and adults alike.
