Page "Crouching Tiger, Hidden Dragon" Paragraph 3

One evening, a masked thief sneaks into Sir Te's estate and steals the sword.

Mu Bai and Shu Lien trace the theft to Governor Yu's compound and learn that Jade Fox has been posing as Jen's governess for many years.

Mu Bai makes the acquaintance of Inspector Tsai ( De Ming Wang ), a police investigator from the provinces, and his daughter May ( Li Li ), who have come to Peking in pursuit of Fox.

Fox challenges the pair and Sir Te's servant Master Bo ( Xian Gao ) to a showdown that night.

Following a protracted battle, the group is on the verge of defeat when Mu Bai arrives and outmaneuvers Fox.

Before Mu Bai can kill Fox, the masked thief reappears and partners with Fox to fight.

Fox resumes the fight and kills Tsai before fleeing with the thief ( who is revealed to be Fox's protegée, Jen ).

After seeing Jen fight Mu Bai, Fox realizes Jen had been secretly studying the Wudang manual and has surpassed her in skill.
