In the army camp, she gets into trouble when the commander demands every soldiers to go through a strip search for suspected theft. Not wanting to strip before everybody, she admits the theft. The strict commander orders Mulan to be bound for execution the next morning. A soldier called Wen Tai (Chen Kun) frees her in a surprise attack by the nomads. Mulan does not escape to go home but rides back to fight. The commander is mortally wounded and his men are about to lose the battle. However, Mulan manages to kill the enemy chieftain and turns the defeat into a victory. Since then, she advances in the army and is finally promoted to the rank of general.
In the army, she develops a romantic relationship with Wen Tai, who is also promoted progressively with Mulan and becomes a general. In an ambush, Wen Tai is severely wounded. He survives the injury. As he does not want to hold back the advancement of Mulan, he does not convey a message of his survival to Mulan. In fact, Mulan thinks he is killed, while he is convalescing in the sick tent.
After years of war, the nomads are weary of fighting and their king is about to quit. Unfortunately, the king is murdered by his son, who seizes the power and gathers 200,000 horsemen to invade Northern Wei again. Mulan proposes to the commanding general to lead her camp to lure the nomads into a valley. After the nomads are trapped, the general will plan to attack from the rear of the enemy. The plan almost succeeds. Not knowing to Mulan, the general is jealous of Mulan's achievements and actually abandons Mulan to the attack of nomad horde. Mulan is wounded and her men are trapped in turn.
Facing an imminent slaughter, Wen Tai suddenly appears behind the lines of soldiers. He walks before the enemy and calls out to the nomads, holding an imperial identity badge. It turns out that Wen Tai is a prince of the Northern Wei Dynasty and has enlisted incognito. He bargains with the nomad king - his surrender for his comrades' freedom.
When Wen Tai is imprisoned, Mulan sneaks into the nomad camp. With the help of a nomad princess, she kills the king. The triumphant Mulan stands in front of the emperor and the prince. She does not want any award and simple asks for her discharge so she can go home.
