In a small mining town in Nevada, Professor Clemens, a scientist played by Christopher Brooks, works on genetic experiments at a local ranch. When a strange explosion occurs at the ranch, Clemens discovers a mutated lamb fetus that begins to grow at an alarming rate. The grotesque creature swiftly becomes a threat to the community. Clemens and his assistant Mariposa attempt to research and contain the abomination, but soon find that controlling such a monstrosity is beyond their scientific capabilities. As fear spreads through the town, Harvey Baylor—a wealthy businessman with vested interests—seeks to exploit the situation for his gains.

Tensions rise as Clemens tries to warn the townspeople about the looming danger, only to be met with skepticism and resistance. The creature starts roaming the countryside, causing havoc and chaos. Meanwhile, Baylor's manipulations spark conflicts within the community, further complicating efforts to deal with the growing menace. Desperation seeps into the fabric of the town as destruction seems inevitable, leading to a climactic face-off between man and monster. The chaotic events ultimately reveal deeper issues within the town's social and moral fabric.
