The catastrophic Time War between the Time Lords and the Daleks erupts, threatening the entire universe.
The Time Lords prepare to defend Gallifrey from Dalek invasion; the fate of Gallifrey hangs in the balance.
The War Doctor is given the chance to use the Moment, a superweapon, to end the Time War by destroying both the Daleks and Gallifrey.
The War Doctor decides to use the Moment to destroy Gallifrey and end the war, causing him great remorse.
The Tenth and Eleventh Doctors arrive through time to confront the War Doctor, leading to a council of three versions of the Doctor discussing the fate of Gallifrey.
The three Doctors discover a hidden plan to save Gallifrey by freezing it in a single moment in time, preventing its destruction.
Using their combined efforts and the Moment's power, the Doctors save Gallifrey by hiding it in a temporal stasis in the Time Vortex.
After saving Gallifrey, the three Doctors part ways; the War Doctor carries the burden of his actions forward, leading eventually to his incarnation as the Ninth Doctor.
