Summary of the movie:

In Narnia, Caspian, a Telmarine Prince, is woken up by his professor, Doctor Cornelius, who informs him that his aunt has just given birth to a son and that his life is now in danger. Doctor Cornelius gives him Queen Susan's ancient magical horn and instructs him to use it if he is in dire need of help. Knowing that his Uncle Miraz would kill him in order to be king, Caspian flees.
Chased by several Telmarine soldiers, Caspian falls off his horse and encounters two Narnian dwarves and a talking badger in the woods. One of the dwarves, Trumpkin, is captured by the soldiers after sacrificing himself to save Caspian, while the other dwarf, Nikabrik, and the badger, Trufflehunter, save Caspian. Not knowing that they are trying to save him, Caspian blows the magical horn, trying to summon help.

In England, the four Pevensie children wait at the Strand tube station for the train to arrive. One year has passed in their world after they left Narnia. Just as the train pulls into the station, the walls start sucking in, and the whole station tears apart to leave the Pevensies in Narnia. There, they discover that Cair Paravel, their castle, had turned into ruins while they were gone.
Meanwhile, Nikabrik and Trufflehunter lead Caspian to the Dancing Lawn, where all the old Narnians have assembled, including the swashbuckling mouse, Reepicheep, and a large number of centaurs and minotaurs. There, Caspian convinces them to help him win his throne back so that he can give them back their land.

The Pevensies save a bound and gagged Trumpkin as they spot two Telmarine soldiers who are about to drown him in the ocean. After the dwarf realizes that the four of them are the kings and queens of old, they set off together. On the way, Lucy glimpses Aslan and tries to convince the others that she's seen him, but only Edmund believes her. After many twists and turns, they eventually encounter Caspian and his troops, who take them to Aslan's How, a huge underground hall built over the Stone Table. From there, Peter suggests that they attack Miraz's castle. Lucy suggests waiting for Aslan to give instructions, but Peter decides they have waited for Aslan long enough.

The Narnians succeed in raiding Miraz’s castle, but Peter calls for a retreat when he realizes that if they keep fighting, all will be killed. Peter, Edmund, Susan, Caspian, and half of the Narnians manage to escape before the gate closes, but the rest are trapped and brutally slaughtered.

When they get back to Aslan's How, Peter and Caspian, who are both guilty and upset over the loss of half their soldiers, have an argument about the attack on the castle, which almost culminates in a swordfight. Later, Nikabrik, along with a hag and a werewolf, draw Caspian aside and tell him that they can help him claim his throne and guarantee Miraz's death. After Caspian agrees, the hag uses black sorcery to summon the White Witch. From inside a wall of ice, the Witch tries to convince Caspian, who had not realized what Nikabrik's true intentions were, to give her a drop of his blood in order to set her free. Peter, Edmund, and Trumpkin arrive and quickly incapacitate Nikabrik, the wolf, and the hag, and Edmund shatters the wall of ice before the Witch can be freed.

As Miraz and his army arrive at Aslan's How, Caspian suggests that Peter and Miraz duel one-on-one under the condition of surrender, in order to buy Lucy and Susan more time to find Aslan. Miraz is forced to accept, as it would look cowardly to refuse to fight a boy half his age. Susan and Lucy, who are searching for Aslan in the woods, are chased by Telmarine soldiers along the way. Susan sends Lucy off and remains behind to deal with the soldiers, but she is soon rescued by Caspian and the two of them return to the battlesite. Peter and Miraz battle, and Peter eventually is able to wound Miraz, but gives his sword to Caspian to finish him off. Caspian, who cannot bring himself to do it, lets Miraz keep his life, but says that he intends to give Narnia back to its people.

Lord Sopesian suddenly stabs and kills Miraz with one of Susan's red-feathered arrows and blames the Narnians for shooting Miraz. Sopesian calls the Telmarine army, which is waiting just outside the How, to advance so that they can obliterate the Narnians. The Telmarines unfurl nasty trebuchets which fire a continuous stream of boulders at Aslan's How and the Narnian army. In an effort to fight back, the Narnians try several tactics, including collapsing underground tunnels underneath the army, and sending griffins overhead with archers in their claws. In one final hope, they charge head on to fight with the Telmarines.


Lucy, meanwhile, has found Aslan in the woods; he awakens the trees that have been in a deep sleep. General Glozelle knocks Caspian down to the ground, but holds back from killing him. Suddenly, the trees around Aslan's How come alive. One of them snags Glozelle and knocks him out cold. With the whole forest suddenly against them, Lord Sopesian has the Telmarines withdraw to the bridge of Beruna, where they are confronted by Lucy and Aslan. Aslan summons the river god, who destroys the bridge and wipes out the majority of the Telmarine army as well as Lord Sopesian; all of the surviving Telmarine soldiers are forced to surrender and hand over their weapons while the Narnians are honoured for fighting well.

Before the Pevensies depart, Peter and Susan declare, much to Caspian, Edmund, and Lucy's dismay, that Aslan has told them they will never return to Narnia. Aslan explains that Susan and Peter have gained everything they could possibly gain from their experiences in Narnia and are no longer needed there. Susan and Caspian share a kiss, knowing they will never meet again. The Pevensies then go back to England, leaving Caspian as King of Narnia.

It's not the last farewell ♥
