Harry and the Hendersons

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 exame 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. In their attempts to keep Harry a secret, the Henderson's have to hide him from the authorities and a man, who has made it his goal in life, to catch a "bigfoot".
