Quick recap
Lord Shen, a banished peacock, returns to Gongmen City with a new weapon, the cannon, that could end kung fu. Po and the Five set out to stop him. Along the way, Po has flashes of being a baby and asks Mr. Ping where he came from: he was found in a radish crate. He learns Shen attacked the panda village years ago and that his mother hid him to save him. Shaken, Po nearly dies. A soothsayer helps him accept his past, and he finds inner peace. With it, he sends Shen's cannonballs back and defeats the villain. In the end, far away, Po's father senses his son is alive.
