Syaoran, Kurogane, and the other dimension travelers set out to steal a national treasure that can help them find one of Princess Sakura's memory feathers.
In order to retrieve Sakura's feathers and save her life, the travelers must sacrifice what they value most to Yuko, a witch who can grant them the power to cross dimensions.
Two Syaorans embark in a battle to the death over Princess Sakura's feathers and the princess herself, leaving the Princess caught in the middle of the ultimate battle between good and evil.
Syaoran, Fai, Kurogane, and Mokona return to the Kingdom of Clow for a showdown with Fei-Wang Reed, where their presence endangers the very existence of the once happy villagers.
Syaoran and Princess Sakura's mysterious past is finally revealed as the princess's seventh birthday draws near, and Syaoran is forced to protect her from a powerful enemy who plans to condemn the royal youngster to death.
The travelers head for Fei-Wang Reed's dimension to recover Sakura, but are unaware that Fei-Wang is ready and waiting; meanwhile, Syaoran is shocked when Yu?ko finally uses the odd cylinder she has been holding on to.
Syaoran battles Fei-Wang Reed, who is willing to destroy the universe to fulfill his evil plans, but a secret from Sayoran and Sakura's past may unlock a terror that will plague humanity for all eternity.
Syaoran managed to prevent Sakura's death by turning back time just moments before it happened, but now that moment in time has come again and Fei-Wang is determined that Syaoran will not undo his plans again. The final battle begins and, if Fei-Wang wins, Sakura will die.
