"Reverse Leap" tells the story of 17-year-old volleyball player Jiang Linya, a patient with congenital heart disease, who sneaks into the gym to train late at night and is caught by retired player and security guard Ji Qiongye. Ji Qiongye, who had retired due to a heart disease, discovered her persistence and potential, and turned into a "devil coach" to help her break through her physical limits with professional training and her own experience at the training ground in the early morning. Two souls "smashed" by fate, in the resonance of volleyball and heartbeat, write a passionate chapter against reality and self.
