Wu Jiuxiu (Josie Ho) was once a very professional badminton player with great skills. However, an accident caused her to give up her career and her life fell into a trough. One day, by chance, the sloppy and confused Wu Jiuxiu met the gangster Liu Dan (Ekin Cheng) and his friends. Although Liu Dan looked sloppy and unserious, he actually had a kind heart. Wu Jiuxiu became the badminton coach of Liu Dan and his group. In the process of teaching skills, Wu Jiuxiu gradually regained the feeling of being a powerful player in the past and decided to treat life and himself well. Liu Dan also found the hope and meaning of life in sports and sweat. Three laymen who knew nothing about badminton actually played well under Wu Jiuxiu's training.
