T-Bag and T-Shirt have now gained possession of a large, flying cup and saucer which hovers in space above the Earth. Whilst reading an account of her cousin, Kit Bags final adventure into some peruvian jungly type place (Kit Bag was a famous explorer), she finds out about the lengendary Sunstones of Montezuma and how they can grant the power of the sun to whoever lays them on an altar in an Aztec temple in the jungle (all this sounds quite familiar!). She sets off to find them, but is foiled by an archaeologist (Diggory) and his daughter Penny who scatter the sunstones as T-Bag is claiming the power of the sun.
