Publisher's summary
The time has arrived. Events are in motion. The end of the universe is at hand and the Doctor and his friends have one hour to save eternity. Starting now.

Plot
Padrac admits Caleera into his office, having sent the Eleven to fetch her. He charms her, telling her that Gallifrey needs her and saying that she is very special.

Locked onto the Eleven's Time Ring, the Doctor, Liv and Helen travel to Gallifrey an hour before the time stipulated by the Doomsday Chronometer and are impeded by the transduction barriers, forcing them to materialise in real space to complete the journey.

Now Lord President, Padrac tells the Sonomancer to enter the now complete Resonance Engine, saying that the pain she will experience is necessary. She agrees to.

Whilst the TARDIS lands outside the Capitol using codes remembered by the Doctor, the Eleven finds that he has been prevented from returning and that the Doctor was right about Padrac. Holding the Eleven at gunpoint, Tessno confiscates his Time Ring and prepares to kill him before the Doctor arrives, convincing her that the Eleven could help them get into the Capitol.

Tessno takes the group to the opposition, led by Councillor Alekall in a tent. The Doctor asks the Eight what Padrac is planning and learns about the Resonance Engine and the access tunnel to the Capitol which Padrac closed off. The Doctor takes his Time Ring and uses the psychic cloak to disguise himself as the Eleven, tasking Helen with evacuating the Time Lords and Liv and Alekall with placing bombs around the transduction barriers once he is able to drop the force field for a brief time. He tells them that doing so will force the Sonomancer to chose between ending the universe and saving the planet from the alien ships above.

Padrac and Ladonne help the Sonomancer into the Resonance Engine, causing her pain. He makes a speech reassuring the Time Lords about the barrage and the safety of Gallifrey when the Doctor arrives, disguised as the Eleven. After seeing the Resonance Engine, he heads to look at the shields, leaving Padrac and the Sonomancer to discuss the Eleven's further uses. Padrac departs and has Ladonne step up the power.

In the TARDIS, Alekall gives Liv a staser and materialises inside the Capitol once the Doctor has the field down. Although the Doctor tries to keep their presence secret, Padrac sees them both on a monitor.

The Eleven is guarded by Tessno and asks her why she hates him so much. She tells him that her squad had once caught the Ten on Dalgar before he hypnotised them, having them shoot and kill one another and forcing her to shoot her friend. The Eleven convinces Tessno to untie him so that she might kill him, giving her the opportunity to steal her staser and kill her.

Liv and Alekall reach the engineering section of the Capitol and flee from Time Lord guards. Meanwhile, the Doctor approaches the Sonomancer in the Resonance Engine and tells her that he thinks the resonance will build uncontrollably and that she will die when she tries to destroy the universe. When Padrac enters, the Sonomancer chooses not to ask about the Doctor's claims.

The Eleven holds Helen hostage and the Five taunts her by saying that they would have preferred Liv as a hostage. The Eleven shoots a Time Lord and steals a Battle TARDIS.
