Choi Kun-Lun, the flying thief (Lo Lieh), tells the scholar that stealing other men's wives requires good lovemaking skills and equipment. He promises to help the scholar only if he has a horse's penis. Of course, the thief does not think it is possible, until the scholar returns one day, indeed, with a horse's penis attached as his own. Apparently, the scholar met a doctor (a cameo by Hong Kong comedian Kent Cheng) who was able to replace anatomical parts.
