Someone saw "Airplane" one too many times. Maybe two too many times. A loving cheapjack tribute to 50's sf films, The Nake Monster has a 3 eyed giant giving our heroes trouble. The Government and the local sheriff rehire Kenneth Tobey (of "The Thing" fame) to help stop the monster.
Lots of bad puns and slap stick happen. This isn't neccesarily bad. Lines like: "It's come over that mountain!" "It's a butte." "I don't know, it seems nice enough." are just horrid but still make you smile. This is the Junior High School version of "Airplane," and I for one didn't mind it at all.
