Track of the Moon Beast

After a meteor storm, a fragment buries itself deep in the skull of Chase Cordell (Paul G. Carlson), and the change starts once the sun goes down. At night he becomes a giant reptilian creature that goes out killing, while Professor Johnny Longbow Salinas (Gregorio Sala) finds ancient Native American paintings of the same event centuries ago. Leigh Drake (Kathy Nolan), who still loves him, refuses to give up on the man he was.
