Po's popularity is gone after wicked weasels steal a powerful gauntlet. English knight Wandering Blade offers a chance to chase down the thieves.

Po is ready and willing to be Blade's apprentice. But their mismatched personalities clash — until Po's masterful kung fu moves impress his partner.

A mysterious figure helps Po. Po and Blade must put aside their differences when they stumble into Klaus and Veruca in the desert spice market.

Veruca's magic powers are of no use, so she seeks to treat her injured brother in a secret forest village. But Po and Blade are right behind them.
