Publisher's summary
Our yearlong celebration of Doctor Who's 50th anniversary concludes! All eleven Doctors must team up if there’s any hope of defeating his latest and most surprising adversary! Everything has been leading up to this epic conclusion!

Plot
The Eleventh Doctor summons his other ten selves. Adam decides to kill all the companions, but it is revealed his remote is Frobisher in disguise. The Eleventh Doctor says he left a chronal trail, which enables the TARDISes to merge and bring the Doctors here. Adam and release an Auton army. However Frobisher, disguised as an Auton, overpowers Adam and releases the companions. A fight between the "armies" breaks out, during which the Master reveals his plan to destroy all of reality itself.

He tells the Doctors that his ultimate victory will be making all of his incarnations watch as he does so. The 9th, 10th and 11th Doctor plead with Adam, saying they will take full responsibility for what happened in his life and that he is many things, but not a murderer. The 9th Doctor asks him to prove him wrong, to show him he misjudged Adam. Convinced by the Doctors, Adam stuns the Master and tells him he has gone too far, enraged that the Master has been using him all along. Annoyed by Adam's suddenly developed conscience, the Master stabs him with a hidden Knife, after which the injured Adam uses the Time Manipulator to teleport to the console behind the Master.

He destroys it, foiling the Master's plan, but the resulting explosion only injures him further. The Master, still pleased by his role within all the chaos, teleports away, escaping the Doctor.

The Doctors consult a dying Adam, telling him that they were wrong about him. He asks "Maybe I would have been good enough after all, eh Doctor?", before dying in the arms of the Doctor and his companions.

All the Doctors and companions stand around a small stone replica of the Tardis, mourning. As they begin to leave, the 11th Doctor turns around once more to take a look at the inscription: "Adam Mitchell - A companion True."

Continuity
The fact that Amy and Rory are present, even getting one line each, clashes with the fact that the Doctor clearly said he could never see them again, as their death is a fixed point in time and it would create a paradox.
