Tercera película de la saga "Kung Fu Panda", en la que Po deberá hacer frente a dos desafíos épicos: uno, de origen sobrenatural; el otro, muy cerca de su hogar, con la aparición del que dice ser su padre biológico.

Living large and loving life, Po (Jack Black) realizes that he has a lot to learn if he's going to fulfill the next challenge from his beloved instructor (Dustin Hoffman). After reuniting with his long-lost father (Bryan Cranston), Po must transition from student to teacher and train a group of fun-loving, clumsy pandas to become martial-arts fighters. Together, the kung-fu brethren unite to take on the evil Kai (J.K. Simmons), a supernatural warrior who becomes stronger with each battle.
