The Time Soldiers face the twisting passages of an ancient Egyptian tomb, discover a mummy—then accidentally jump backward in time again to meet the boy who becomes the pharaoh... who becomes the royal mummy. They have discovered an amulet, set with a glowing green stone, that apparently allows them to summon the time portal at will! But they have to escape the pharaoh’s palace guards and recover the amulet from a thief in order to make it home.
