On the desolate planet of Telos an archaeological team from Earth is using explosives to gain access to an underground chamber. The Doctor, Jamie, and Victoria arrive to discover that they are searching for the fabled lost 'Tomb' of the Cybermen who all mysteriously vanished some 500 years earlier.
Inside they discover the entrance to a vast icy hibernation unit containing the last remnants of the Cybermen, frozen and unmoving. However, the Doctor soon becomes aware that not all of the team have joined the expedition out of scientific curiosity and that there are those in their midst who wish to revive the silver giants.
Soon the ice begins to melt and the Cybermen return to life, along with their rodent-like servants, the Cybermats. The Doctor must quickly find a way of stopping both the Cybermen and the human traitors before their menace is once more unleashed upon the galaxy.
