That sarsaparilla drinkin', guitar strummin' cowboy crooner Tex Ritter is back in White Flash's saddle for this shoot-'em -up adventure. Tex Martin and his side-kick Stubby are peacefully roaming the range when they discover Tom Wilson brutally shot and mortally wounded. Tom informs his friend Tex that the merciless Masked Riders have stolen his deed to the Four-Star mine. Determined to avenge Tom's murder, he rides into town and encounters the saloon boss, Norton , and his strong-arm varmint Blackie Devlin , who force Tex into a no-holds-barred barroom brawl. Tex soon learns that these villains are behind the Masked Riders' pillaging terror and sets out to foil their plans by infiltrating the gang as a hooded-costumed member! The Mystery of the Hooded Horseman is a fine example of the many Tex Ritter westerns that were produced by Edward Finney. The unbridled gunfights and galloping action sequences effectively contrast the placid, easygoing charm of Ritter's personality and singing.
