Doctor Who: The End of Time 10th Anniversary

In “The End of Time,” the Doctor’s psychotic nemesis the Master (Simm) has been reborn. Reunited with his friend Wilfred Mott (Bernard Cribbins), the Doctor desperately tries to locate the Master only to find that an even greater danger is approaching. As a terrible shadow falls across the entire universe, an ancient trap closes around the Earth. With the sound of drums growing louder, the Doctor and Wilf must fight alone. But sacrifices must be made, and a deadly prophecy looms: “He will knock four times.”
