Gabe visits his Uncle Ben and cousin Sari in Egypt over winter break. While exploring tunnels in the Great Pyramid, Sari disappears down a narrow passageway, playing a trick on Gabe. Later at the Cairo Museum, they are kidnapped by Ahmed, an Egyptian scientist, but escape. They return to find the pyramid, where Gabe and Sari become separated from Uncle Ben. They discover Ahmed's secret chamber of mummified bodies. Ahmed tries to mummify them as well but is stopped by Uncle Ben. Ahmed is ultimately defeated when Gabe uses a mummy's hand to summon the others and send Ahmed into the flames.
