Mulan wants to carry on her father's legacy by joining in the ranks, so she disguises herself as a male. Eventually, they are able to get to the training camp, and end up getting into a fight with some of the other recruits. After being rejected by the Captain, Li Shang, Mulan wants to prove her worth by taking on a series of challenges. After they successfully complete the challenges, Li Shang the recruits head out to scout the nearby snow-capped mountains. Mulan reveals to the Captain that she knows where Shan-Yu is.

Eventually they reach a cave that has been overrun with Heartless, and once they escape they manage to cause an avalanche that almost kills everyone. In the mean-time, the entire training camp has been destroyed by Shang-Yu and his army, Mulan is discovered that she is not a man and is throw out of the army along with Sora, Donald, and Goofy. After they overhear Shan-Yu's yell from a far distance they go to warn Li Shang, who in turn, doesn't believe her.
