Swordsman II continues the story from Swordsman (1990) with an entirely new set of actors.
Blademaster and his martial arts school decide to retire to a distant mountain.
Before leaving, he visits his friends, a tribe of snake-wielding women warriors.
He finds that they have been attacked, and their leader, Princess Yin-Yin, has been abducted by her evil uncle Fong.
Fong overthrew Yin-Yin's father years before and took over their sect.
Fong also has possession of a sacred scroll which reveals how to achieve ultimate martial arts power.
Blademaster decides to help Yin-Yin and her imprisoned father.
His romantic complications deepen when his childhood chum and Yin-Yin are joined by a new rival.
Blademaster thinks the new rival is an innocent village girl he has saved, but she is actually Fong in disguise!
The process of gaining ultimate martial arts power requires self-castration and transmogrification into female form.
