In the early third century, the land of China is in turmoil, on the brink of a massive civil war. The ambitious and ruthless Prime Minister Cao Cao seeks permission from the Han dynasty's weak Emperor to organize a southward-bound mission supposed to subdue the warlords opposing his rule. Under the guise of removing rebels, Cao Cao's real intention is to bring all of China under his control. With a vast army at his command, he quickly conquers the northern kingdoms and sets his sights on the southern provinces, which are the only remaining obstacles to his complete domination of the empire. The southern warlords Sun Quan and Liu Bei, despite initial reluctance, realize the gravity of the threat and decide to form an alliance to oppose Cao Cao's overwhelming forces.

As Cao Cao's massive navy moves southward, the allied forces of Sun Quan and Liu Bei face the daunting task of strategizing against a seemingly unbeatable opponent. With the help of brilliant military strategist Zhuge Liang, they set their plan in motion on the eve of a decisive battle near the Red Cliff. Utilizing their intimate knowledge of the local terrain and employing ingenious tactics, they prepare to face Cao Cao in a battle that is both a fight for survival and a pivotal moment in Chinese history. Despite their smaller numbers, the unity and cunning of the allied forces aim to exploit their enemy's weaknesses, setting the stage for an epic confrontation.
