The Doctor and Wilfred become fugitives from the Masters, and take refuge on the Vinvocci spacecraft to strategise.
Meanwhile, the Lord President, following a prophecy about the future of the Time Lords after the Time War, implants the sound of drums in the Master's head as a child; in the present, the billions of Masters amplify that signal. Still needing a focal point, the Lord President orders a whitepoint star to be launched to Earth. The Master collects it and uses it to create a strong link that allows the Time Lords to bring Gallifrey out of the time lock they were stuck in and in close orbit to Earth. The Lord President and a small ensemble of Time Lords appear in Naismith's mansion.
The Doctor fears the horrors that Gallifrey will bring to Earth, and as the Vinvocci bring their ship to land, the Doctor jumps from it into Naismith's mansion, armed with only Wilfred's gun. The Doctor finds himself torn between shooting the Master or the Lord President to sever the link and return Gallifrey to the time lock. Among the Lord President's ensemble, the Doctor spots the same woman in white Wilfred had seen, who silently communicates to him with her eyes. The Doctor understands, and fires the gun at the whitepoint star instead, shattering it. As Gallifrey is pulled back, the Lord President, revealed to be Rassilon, attempts to kill the Doctor, but the Master intervenes, saving the Doctor and seeing his act as revenge for what the Time Lords had done to him. Soon after, the Master, the Time Lords, and Gallifrey have disappeared, and humanity has been restored.
The Doctor considers himself victorious until he hear four knocks. He finds Wilfred had come to help him, but is now trapped in one of the Gate's isolated control rooms that is about to be flooded by radiation. The Doctor self-sacrifices himself by stepping into the other, freeing Wilfred before the room is flooded. Though his body was able to absorb the radiation, the Doctor knows his body will soon regenerate. After dropping Wilfred back home, the Doctor visits past companions and acquaintances; Martha Jones (Freema Agyeman) and Mickey Smith (Noel Clarke) who have married and are working as freelance alien hunters, Sarah Jane Smith (Elisabeth Sladen) and her son Luke Smith (Tommy Knight), and Captain Jack Harkness (John Barrowman). He also visits Verity Newman (Jessica Hynes), the great-granddaughter of Joan Redfern who the Doctor had previously met in "Human Nature". He then travels forward in time to Donna's wedding where he gives Wilfred and Sylvia Noble (Donna's mother) a lottery ticket that he had bought for Donna with money borrowed from her deceased father. Finally, the Doctor visits Rose Tyler (Billie Piper), on New Year's Day 2005, three months before she meets him as the Ninth Doctor and tells her she will have "a really great year".
As the Doctor succumbs to the radiation on his trip back to the TARDIS, the Ood sing "Vale Decem" (Goodbye Ten). Inside, the Doctor sets the TARDIS in flight before shouting "I don't want to go" and then regenerates into the new Doctor (Matt Smith). He inspects his new body before realising he is crashing. He screams "Geronimo!" as the TARDIS hurtles back to Earth.
