The walls are stronger. The enemies are fiercer. The stakes have never been higher. In the aftermath of the brutal war that almost tore China apart, The Great Wall stands as a testament to survival — but even the mightiest fortress cannot protect what lies within. As a new threat emerges from the shadows, it is not only the walls that must endure… but the hearts of those who stand to defend them.

William Garin (Matt Damon) returns, now a battle-hardened leader torn between duty and the love he has left behind. Amidst the howling winds and freezing nights, the Wall is no longer just a barrier against monstrous creatures — it is a symbol of the cost of war, of what must be sacrificed for peace. Lian (Zhang Ziyi), who has been scarred by the battles of the past, must choose between vengeance and redemption, while the fate of millions hangs in the balance.
