Newly Mastered in HD from a 4K scan! A gang of vicious crooks has been running guns and ammunition out to foreign revolutionaries. Gordon MacKnight (Pierre Watkin, Meet John Doe) is the mastermind behind these elaborate schemes – hijacking freight trains and killing the crews, leaving no witnesses. Sheriff Tad Osborne (Will Wright, Adam’s Rib) is discouraged and has not been able to catch the killers. His niece Dixie (Penny Edwards, Trail of Robin Hood) urges him to quit while he can, but when Roy (Roy Rogers, My Pal Trigger) and his Purple Sage riders arrive in the border town, they persuade the sheriff to stay in office and help them capture the criminals. MacKnight tries to escape, but Roy and Trigger follow to ride him down and bring him back to justice. Beautifully shot in TruColor by Jack A. Marta (Cat Ballou) and wonderfully directed by the great William Witney (Daredevils of the Red Circle).
