Luggage of the Gods!

A small tribe of cavepeople are alive and well and living today somewhere in uncharted North America. Their only contact with the outside world is the frightening sight of a passing jet. When an airliner in distress jettisons its cargo near their village, cave painter Yuk violates tribal taboo and looks up at the plane. He is banished from the tribe along with his best friend Tull, and separated from his sweetheart Hubba, the lovely cavegirl. Alone and afraid, Yuk and Tull stumble upon the smorgasbord of luggage that fell from above. The movie follows Yuk's adventures as he tries to use the modern artifacts to overcome his obstacles and change his cave life forever.
