Plot
In 1000s Ireland, Irish warlord Aengus sits down to talk to a "ghost" of one of his fellows warriors. It reveals that it is one of the Gelth and they wish to invade Earth. Aengus then shouts out to summon "the Doctor".

In 2013, the Doctor is sitting in his TARDIS reading A Christmas Carol (a reference to the original episode where the Gelth appeared) when he gets a call from Torchwood. They tell him they've found something and would like him to come in.

Captain Jack Harkness meets him and takes him inside. He shows him an old Irish tapestry with the words Dochtuir teacht anseo. The Doctor translates it as : Doctor come here. Captain Jack then states that they calculated the age of the tapestry and it came from 1023.

The Doctor returns to the TARDIS and heads back into 1023, Ireland. There he gets out and meets Alana ,an 8 year old girl. Alana asks him what he's doing and the Doctor asks her to take him to Aengus.

She takes him to her father, Aengus. Aengus reveals that a race known as the Gelth have threatened to invade Earth. Then Aengus asks the Doctor to look after Alana. The Doctor accepts and takes Alana to his TARDIS. When asked about her family, Alana says her grandfather was named Lochan (this is supposed to mean that Amy Pond may be a descendant of her because Lochan means pond and Ireland and Scotland have shared histories). The Doctor and Alana arrize on Umanda, the "most perfect babysitting planet in the world".

There they discover an Ood who is uttering a message : Liars make false ground. The Doctor than asks who he is really talking to and the Ood answers : The Last. The Ood then goes on to say that the Doctor lies about his age, but it is accepted as fact. The Doctor than tells the Ood to shut up and it has a stroke and dies. Shocked, the Doctor leaves Umanda with Alana and go back to 1023.

Once in 1023, they find themselves up against what seems like an undead army. The Doctor than demands to speak to the Gelth and theyarrive. They recall how their bodies were lost in the Time War. The Doctor than offers them a body. He claims that it can contain all of them. He then uses the time vortex to trap them in the bodies of royal drone robots of Umanda.

There the Last reveals himself in the form of a young man. The Doctor asks who the Last is and he (the Last) states that he is the oldest being in the universe. . The Last then asks the Doctor his age to which he replis that it is 1207. The Last than shouts that the Doctor is lying and the Doctor objects. The Last then turns into a time fissure with a face. He warns the Doctor to not take sides in the upcoming conflict. When the Doctor asks which conflict, the Last dissapears.

In the National Gallery, the Last appears. He then takes the form of a curator (played by Tom Baker).

The episdoe ends with the Doctor calling Coal Hill Secondary School, leading to the vents of The Day of the Doctor
