Returning from a hunting trip in the forest, the Henderson family's car hits an animal in the road. At first they fear it was a man, but when they examine the "body" they find it's a "bigfoot". They think it's dead so they decide to take it home (there could be some money in this). As you guessed, it isn't dead. Far from being the ferocious monster they fear "Harry" to be, he's a friendly giant.
Young fantasy and science fiction aficionado Gavin Gore and his friends stumble onto some huge footprints in the woods. A local cop, reporter, and a renowned Sasquatch authority investigate, while two of Gavin's dim-witted neighbors hatch a scheme to profit from the situation.
