Horror western written and directed by Fredric Hobbs. Local rancher Eddie (Richard Marion) discovers a large mutated sheep embryo in an old mine in Nevada. Professor Clemens (E. Kerrigan Prescott) and his assistant Mariposa (Karen Ingenthron) study the find as they are anthropologists drawn to the mines because of their role in a local legend about a monster that haunted the area. When the embryo is incubated, it grows into an eight-foot-tall mutant sheep monster which escapes from the lab and threatens the local population.
