During the Republic of China, Chen Shi (Liao Fan), the heir of the Southern Wing Chun, came to Tianjin and met Zheng Shan'ao (Jin Shijie), a master of Tianjin martial arts. In order to gain a foothold in the martial arts world, Zheng Shan'ao suggested that Chen Shi use the traditional method of teaching apprentices to kick the gym to achieve his goal. After many twists and turns, Chen Shi married Zhao Guohui (Song Jia), a beautiful woman from Tianjin, and also accepted a local youth Geng Liangchen (Song Yang) as his apprentice to kick the gym on his behalf. The couple temporarily lived in the slums to prevent the enemies who kicked the gym from coming to seek revenge. Chen Shi and his wife originally looked down on Geng Liangchen, who was aggressive and lustful, but after contact, they also discovered Geng Liangchen's merits. However, with the intervention of Zou Guanzhang (Jiang Wenli), the director of the eighth martial arts gym, and Lin Xiwen (Huang Jue), a military figure, the martial arts world in Tianjin is facing a huge change. The desire to revive the family business through martial arts, his love for his wife, and his responsibility as a master have put Chen Shi in a dilemma.
