On the day of transfer, Leng Ao's school boy Lu Yunchuan knelt down in public, stopped Shen Nianzhi's suitcase, and begged her not to leave. Everyone thought he was trying to retain his childhood sweetheart Han Yutong, but he stared intently at the old pocket watch on Shen Nianzhi's wrist whose hands stopped at 15:47. The savior he had been looking for for many years was right in front of him, but Shen Nianzhi didn't recognize him at all. Han Yutong has a hidden backhand, Cheng Shu has old photos, the clock shop owner Su Wantang conceals the secret of the serial number, and the student union Chang Jiang Xun controls the surveillance. Shen Nianzhi's pocket watch became the hottest evidence in Jianglin City, and the transfer was just a carefully arranged miscarriage of justice.
