It's been a while since Mulan returned home. Her lover, General Shang, asks the girl's hands and receives a positive response. A faithful guardian dragon Mushu is happy with their happiness. But soon he finds out that after the wedding he will lose his ward, as such is the tradition.
At this time, the emperor receives the newly-made fiancé and the bride to accompany his daughters to the neighboring kingdom. There, three young girls must marry in order to make the ruling yards form an alliance, and together they resist the possible attack of the Mongols.
On the way, the princess falls in love with the accompanying soldiers of Shang. And without that undesirable forthcoming marriage, becomes for girls an unbearable burden. Mushu is deliberately seeking a quarrel with Mulan and his fiancé. He quickly regrets his action, but does not have time to change what he has done: the fight with the robbers leads Mulan and Shang to the ruined rope bridge, saving the beloved, the general releases her hand and falls into the abyss.
Mulan will have to forget about his problems, save his relations with the allies and, at the same time, prevent the princesses from sacrificing themselves.
