First-year student Liu Xiangyun is kicked out of the gym after losing a table tennis match. On Teacher Zhang’s suggestion, he heads to the table tennis table behind the supposedly haunted cafeteria in the West District to practice. There, he unexpectedly finds a phone card, whose owner turns out to be Wang Lingling, a senior who died by suicide years ago. Wang Lingling asks Liu Xiangyun to give the card to Teacher Zhang, uncovering the story of how the two were forced apart by circumstances and how Wang Lingling took her own life. Teacher Zhang has carried guilt for years, while Wang Lingling has continued to stay by his side in her own way. In the end, holding on to his belief that “Wang Lingling is helping him,” Liu Xiangyun overcomes his inner demons in the table tennis finals and defeats Da Fei, a three-time champion. He also realizes that true strength comes from believing in himself.
