When one of them is discovered to be a Master's daughter, and the other a male student of the same Master, the Furious Five and Po are stunned. When troubles arise in the Valley of Peace, Leopardess and Lye Shang must prove themselves to the Masters. As time passes, and evil approaches at every growing second, they learn about themselves...and just how much they love each other.
