After spending the night in a museum case, Benny leaves the Modern Museum of Ancient Art with a priceless Egyptian scarab pinned to his jacket. Thinking it's a bauble, Top Cat offers it to Fancy-Fancy to use in impressing the lady cats. But soon the gang realizes the jewel is genuine, and they sneak back into the museum to return it. They are caught by Dibble, who charges them with stealing the entire collection. While the cats try to straighten the situation out, the real jewel thief appears and is apprehended.
