Ordinary American family vacationing in the Northwest has a collision with Bigfoot. Thinking that the big guy is dead, they throw him on top of the car and head home. Lo and behold, he revives and starts wrecking the furniture and in the process, endears himself to the at-first frightened family. Nice little tale efficiently told, with Lithgow fine as the frustrated dad trying to hold his Bigfoot-invaded home together. Basis for the TV series.
