The force that has brought three Doctors to the same deceptively nondescript basement vault is driven by hunger, an all-consuming hunger greater than the raging energies of the time vortex itself. It feasts on the transcendental flesh of god-like Chronovores, and it saps the artron emissions from prototype Sontaran timeships. Unchecked, it will devour the TARDIS whole. Putting aside their differences to investigate this ravenous presence, the Doctors discover that beyond the underground labyrinth stands a house unlike any other, where spacious halls and tastefully decorated lounges conceal an architecture that mocks the laws of physics, and each door and window opens onto a different time and place. Reality itself is but a pabulum here, for this is the house that eats time!

Deconstructing the deadly mysteries of this astonishing structure requires a coordinated effort across three distinct timeframes, moments in history infected by its corrupting influence. In each of these eras, a Doctor must face a gauntlet of terrors, for the paradoxes produced by this insatiable beast of an abode have attracted some of the universe’s most dangerous temporal parasites. But there is hope to be found in these distant times and places, for a lone figure is present wherever the Doctor ventures. Earth’s history and the survival of the TARDIS may depend upon the kindness and goodwill of one Dr. John Smith, an ordinary Englishman caught up in most extraordinary circumstances.

Three Doctors. Three timeframes. One monstrous threat. It’s time to bring down the house.
