The martial artist Chen Houde opened Baozhilin in the United States, and he invited his domestic apprentice Ajie to come to the United States to help him many times. Ajie is late in the future. At this time, Johnny, Chen Houde's American disciple, perfidiously challenged his master in order to make himself famous and strengthen his martial arts school. Chen Houde was severely injured by Johnny, but fortunately a girl named Anna rescued him, and Anna hid Chen Houde to heal his injuries. Ajie came to Hong Kong at this time and ran into trouble as soon as he got out of the airport. Ajie was able to solve it smoothly with his kung fu. After seeing Ajie's kung fu, three teenagers insisted on worshiping him as their teacher, but Ajie couldn't help them and had to temporarily accept him to appease them. Ajie came to Chen Houde's Baozhilin, but found that Chen Houde was missing. At this time, Johnny was also looking for Chen Houde. With the help of Anna, Ajie finally finds Chen Houde and learns what Johnny has done to Chen Houde. In order to protect Baozhilin and resist Johnny's troubles at any time, Ajie intensively trained the three cheap apprentices, and the three apprentices' martial arts improved by leaps and bounds. Ajie had to plan to return to the mainland because his passport had expired, but when he learned that Johnny had kidnapped Anna, Ajie's anger was ignited again..
