The three students are Tim, Tanya Yazzie, and Leslie Ann Walker. The locals at their destination think it is ridiculous, and that there is no such creature. But when camping out at night, something dark is detected in the wilds. Doc then meets Deputy Williams, who was attacked by the monster’s child in his home. Williams directs Doc to a bearded mountain man named Crenshaw, who he says has some information on the beast. Doc and his small town students find the old hillbilly.

Lockhart discovers that Crenshaw is harboring a secret baby creature in the rundown shack that it is his home. The professor sees that the small animal is sick. Doc is insistent that he wants the mother killed. However, will she return to save her sickly child? Or will it be Bigfoot instead that finally shows its face?
