Drawn by strange cries coming from the necropolis at the foot of the pyramids, Papyrus comes face to face with Anubis, the god of the dead. The jackal-headed god, angered by a rash of grave robbing, orders the young Egyptian to enter the Great Pyramid and retrieve there the heart scarab of Kheops. But the pyramid is already 1000 years old to Papyrus, and robbers have long ago desecrated it. The young boy will have to search it from top to bottom.
