Cairo, 1933. The Egyptian capital is a buzzing hive of treasure-hunters, thrill-seekers, and adventurers, but to 12-year-old Ronald "Rocket" Robinson, it's just another sticker on his well-worn suitcase. All that changes when Rocket and his pet monkey, Screech, find a strange note written in Egyptian hieroglyphs which launches Rocket into an adventure more incredible than anything he's ever seen at the Saturday matinee. Guided through the secret subterranean world of Cairo by his new friend, a gypsy girl named Nuri, Rocket soon runs afoul of master criminal Otto Von Stürm, who, with his thugs Khalil and Khan, is planning the theft of the greatest treasure in history ---an ancient Pharaoh's fortune, secretly hidden for centuries. But will Rocket and Nuri be able to stop them in time?
