Wen Zhixia, a female physician, rescues three injured tiger cubs, children of the Black Mountain Tiger Lord. Hunter Chen Dashan demands the tigers. Medicine merchant Zhang Changsheng and an evil sorcerer spread plague, setting up a formation for an immortality elixir. Wen Zhixia uses acupuncture to save townspeople, uniting villagers to break the formation. The Tiger Lord seals the sorcerer; cubs recover and return. Rare herbs appear outside her clinic, repayment from the tigers.
