Throughout the emptiness of space, a message is being broadcast on an endless loop, warning any that hear it of an ancient, unfathomable evil. A message that simply states "Beware Sutekh!"
This week Paddy and Tricia watch as The Doctor and Sarah Jane arrive back in England during 1911 and find themselves in a race against time to stop this ancient evil from being released. Just who is Sutekh and why does he frighten The Doctor? All will be revealed in the Pyramids of Mars.
