A Hollywood filmmaker (Mike Jittlov) makes a short for an evil film studio. Unbeknownst to him, the producer has placed a bet of $25,000 that he won't come up with anything with a use. Luckily, our film creator gets the help of his friends.
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.
