 A ruthless band of thugs kidnaps a young official to exchange for their leader who has been captured. Golden Swallow (Cheng Pei-pei) is sent to take on the thugs and free the prisoner (who is also her brother). Though she is able to handle the overwhelming odds, she is hit by a poison dart and gets help from a beggar who is really a kung-fu master in disguise (Vueh Hua). With his help, she forms a plan to get her brother back.
