Narnia has had peace and prosperity since the reign of King Caspian X, but Roonwit the Centaur warns Tirian, the latest king of Narnia, that strange and evil things are happening to Narnia and that the stars portend ominous developments.
An ape named Shift has persuaded a well-meaning but simple-minded donkey called Puzzle to dress in a lion's skin and pretend to be the Great Lion Aslan. Using Puzzle as his pawn, Shift convinces the Narnians that he speaks for Aslan. Once the Narnians are convinced that Aslan has returned, Shift orders the Narnians to work for the Calormenes, and to cut down Talking Trees for lumber. The money will be paid into "Aslan's" treasury, held by Shift, on the pretext that it will be used for the good of the Narnians.
King Tirian and his friend Jewel the Unicorn at first believe the rumours of Aslan's return, but realize the lie when they hear Shift telling the Narnians that Aslan and the Calormene god Tash are one and the same. When Tirian accuses the ape of lying, the Calormenes overpower the king and bind him to a tree. He calls on Aslan for help and receives a vision of Digory Kirke, Polly Plummer, Peter Pevensie, Edmund Pevensie, Eustace Scrubb, Lucy Pevensie, and Jill Pole, though he does not know who they are. (Susan does not appear because she has stopped believing in Narnia, thinking of it only as some silly childhood game she had played when she was younger and immature.) The people in the vision also see Tirian and, though Tirian can't speak to them, they guess he is a messenger from Narnia. A few minutes later by Narnian time – although a week later from their perspective – Jill and Eustace arrive in Narnia. They release the King and rescue Jewel and Puzzle. A band of dwarfs are also rescued, but because their faith in Aslan has been shattered, they refuse to help, claiming "the dwarfs are for the dwarfs". Only one dwarf, Poggin, is faithful to Tirian, Aslan, and Narnia.
Tirian and his small force advance on the stable where the false Aslan is kept, and engage Shift and the Calormenes in battle. All the animals are killed – many by the dwarfs, who attack both sides. Tirian throws Shift into the stable, and Tash, who now haunts the stable, swallows the ape whole. In the last desperate struggle, Eustace, Jill, and Poggin are thrown into the stable. Tirian, left alone and fighting for his life, drags Rishda Tarkaan, the leader of the Calormenes, into the stable.
On the other side of the stable door lies a vast and beautiful land. Much to the Calormen leader's surprise and terror, Tash appears, and snatches him up under an arm. Tirian finds Peter, Edmund, Eustace, Lucy, Jill, Polly, and Digory all standing before him, and Peter orders Tash to leave. Aslan appears, and as they watch at the stable door, all of the people and animals, including those who had previously died, gather outside the barn and are judged by Aslan. Those who have been loyal to Aslan or the morality upheld by Narnians join Aslan in Aslan's Country. Those who have opposed or deserted him become ordinary animals and vanish to an unmentioned place. The vegetation is eaten by dragons and giant lizards. Father Time calls the stars down from the skies into the sea, which rises to cover Narnia. The Sun expands and draws in the moon. Father Time then puts it out, freezing Narnia. Peter closes the door, and Aslan leads them to his country, telling them to go further in to Real Narnia. (Digory alludes to Plato whose Allegory of the Cave describes multiple levels of reality.) They move up a waterfall to some gates and are greeted by Reepicheep as well as meeting other good characters from the earlier novels. They find they can see a real England. Aslan tells them that the English friends of Narnia and the Pevensies' parents have died in a train crash. Susan, who was not on the train, is the only surviving member of the family, The series ends with the revelation that it was only the beginning of the true story
