When an explosion occurs in a classified research laboratory a huge fire erupts and results in a mutated monster known as the OXCOM (Outside Experimental Combat Mammal) escaping and chasing a golden retriever in the same lab through the surrounding woods. The dog outruns it and hides in a barn.
In the barn, Travis Cornell (Corey Haim) is with his girlfriend Tracey (Lala Sloatman). Thinking it is her father, Travis leaves. Tracey discovers the beast and screams, summoning her father who is attacked.
Meanwhile, Travis finds the dog in the back of his car and a military/police force is sweeping the area for the escapees. Travis starts to realize the dog is extraordinary with special powers and decides to keep it. Meanwhile, an NSO agent named Johnson (Michael Ironside) is dispatched by the corporation to retrieve the animals.
