“Lone protector of a terror-stricken family marked for death by an unseen, unknown peril...the mysterious Black Rider!”
A mining engineer teams up with a crusty deputy sheriff to solve the mystery killings at an old mine where the owner's family waits for him to die, and where a valuable radium strike may have been made.
