In the neon-lit urban jungle, the sound of tennis rackets piercing the air is Lin Dan's war song against mediocrity.
He was once the most dazzling rising star in youth tennis, but he fell to the bottom due to a strange suspension. He stayed dormant for three years and made a living by teaching children to play at an old tennis court on the edge of the city. The worn sneakers and peeling paint of the racket could not hide his obsession with victory - until that rainy afternoon, the appearance of professional player Li Bing, like a precise serve, shattered the calm he had deliberately maintained.
Li Bing, a talented girl who has been steadily rising in the rankings, is trapped in a bottleneck period by her inner demons. She saw the possibility of breaking through technical barriers in Lin Dan's seemingly random backhand cuts; and Lin Dan also rediscovered his lost edge in this girl who always had icy eyes. When she made an invitation for "special cooperation training," two souls teased by fate started a tense contest on both sides of the net.
The club's overt and covert struggles, capital's manipulation of sports, and the truth about the ban three years ago gradually emerged. Every swing of the racket is wrapped up with the desire and struggle of the city. While Lin Dan's violent forehand tore through the opponent's defense, it also tore away Li Bing's pretense of indifference; Li Bing's tricky volleys not only won the points, but also intercepted Lin Dan's buried past. They are each other's mirror images and the sharpest opponents. In the center of the sweat-soaked court, they jointly write a passionate epic of urban tennis - when the racket resonates with the heartbeat, even in ordinary cities, fate-shaking ace balls can be played.
