He encounters the Flying Thief, who agrees to help him find women, but only if he attains a penis as big as a horse's. The scholar has a surgeon attach said unit, and he's off and running on his mission, only to find that there are obstacles to his new lifestyle, such as jealous husbands and treacherous females.
