"MYSTERY MAN OF THE BAD LANDS! Neither the law nor the lawless can discover the secret of this two-fisted stranger's past...but they know he's hunting the deadliest killer in the roaring west!"

Wanderers of the West

In this western, a rancher's son rides out for revenge against the rustlers who killed his father. The pursuit stretches between Montana to Arizona and it becomes more difficult because though the son knows the killer's name, he has never seen his face. Fortunately, the killer doesn't know what the son looks like either.
