The Mystery of Lost Ranch

Two men claiming to be scientists arrive in Arizona looking for Blair, a fellow scientist who disappeared while developing a death ray. The men hire Jim Wilson, who finds Blair living with his daughter on a ranch in an inaccessible valley near the Grand Canyon, where the scientist is testing his ray on birds and wild animals.
