Lost in the woods, the Emperor Qi stumbles across local chief Wu Yen, his predestined bride, only to accidentally free a promiscuous fox fairy who promptly falls in love with both of them, changing between man and woman to clumsily woo each, setting the scene for a constantly shifting triangle with the emperor torn between both the fox fairy and Wu Yen and the fox fairy after whichever one will agree to marry her first.
Unfortunately the movie Wu Yen is not yet available on HBO Max.
