UNIT is called in by a radio astronomer whose studies have turned up distinctly unearthly results of late, but even the Doctor can’t imagine the magnitude of the threat. Somewhere within a black hole, a gateway to an antimatter universe, a malevolent being seeks one of his own race to assume his place as the master of a doomed world – and locates a fellow Time Lord on Earth. When the Doctor realizes the nature of the threat, he sends a distress call to the Time Lords, but their power source is also being drained by the black hole, and they can spare no help – aside from sending the Doctor’s earlier incarnations into his own present. The first Doctor is trapped in a time eddy, barely able to contact his future selves, who travel into the black hole – along with Jo, the Brigadier, and Sergeant Benton – to defy the wrath of Omega…the first Time Lord himself.
