A bedraggled and starving rider shows up at a woman's horse ranch in Prescott, Arizona. He does not know his name and has no memory of his previous life. The man is subsequently identified as "Cord Mundy" of Las Cruces, New Mexico, by a pair of local ranch hands of questionable character who claim to know someone who can provide knowledge of his true identity.
As "Cord" searches for this individual, he becomes involved in chasing down a criminal who has murdered a local rancher, stolen a horse, and kidnapped the daughter of another rancher.
Will he finally meet up with the man who can provide his correct name and knowledge of his past history? Is he the real Cord Mundy?
