The Mystery of the Hooded Horsemen is a 1937 American Western film directed by Ray Taylor. It was singing cowboy Tex Ritter's eighth film for Grand National Pictures. While the film had an original copyright notice, its copyright was not renewed, so it has entered the public domain.
Tex and Stubby keep their promise to a dying friend by helping his partner hold on to his gold mine, and to avenge his death by taking on and wiping out a horde of masked riders.
