Zack Mayo is an aloof, taciturn man who aspires to be a navy pilot. Once he arrives at training camp for his 13-week officer's course, Mayo runs afoul of abrasive, no-nonsense drill Sergeant Emil Foley. Mayo is an excellent cadet, but a little cold around the heart, so Foley rides him mercilessly, sensing that the young man would be prime officer material if he weren't so self-involved. Zack's affair with a working girl is likewise compromised by his unwillingness to give of himself.

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.
