Theti-Cheri, daughter of Pharaoh, and her friend and protector Papyrus are on a mission to bring back to Thebes the mummies of 10 archers, long-dead warriors of Pharaoh Sekenenra-Taa. But the mummies lie in the desert, domain of the god Seth, and the malevolent deity will use the dead themselves in his attempts to destroy the intruders. Papyrus and Theti-Cheri will have to fend off wave after wave of evil mummies in order to survive and carry out their sacred mission.
