Slapstick handyman Ernest is in love and wants to buy a bauble for his gal Renee, so he goes to a local flea market and buys a couple of shiny faux jewels. He has no idea that they are real and that they were stolen from a sacred African idol by a crooked adventurer. He also does not know that a villainous Arab prince is impatiently waiting for the stones to arrive. and so he thinks nothing of making the cheap "rocks" into a yo-yo. When the explorer's henchmen discover that the witless Ernest has the jewels, they kidnap him and his girlfriend to the "Dark Continent" where they have all kinds of crazy, comical adventures.
