Fourteen-year-old Lin Wanxing is timid and timid, living alone in the old Wutong community left by his parents, guarding an old yellowed notebook and a polished old key, and has been avoiding the truth of his parents' "accidental" death for six years.
Until one late night, a strange knock on the door broke the dead silence. The door did not move, but the key was quietly moved; the closed old notebook opened automatically, and the mother's cryptic handwriting contained a "danger" warning; in the darkness, a cold gaze followed closely, and a hoarse voice whispered in the ear: "Find it..."
Rumors are spreading in the neighborhood, and the abandoned old building hides secrets. She is surrounded by layers of mysteries about her parents' anomalies before their death, old cases that were framed, and the mysterious "shadow man." The timid girl was forced to step out of her comfort zone, and accompanied by the gentle and protective convenience store owner Shen Zhiyan and her neurotic best friend Su Ran, she explored the truth step by step.
When the old case surfaced and the truth of the "accident" was revealed, she discovered that her parents' death was never an accident, and that the shadow chasing her for the "truth" had hidden difficulties and obsessions behind it.
The night lights are dimly lit, and strange shadows follow. A search for redemption and truth slowly begins in the middle of the night in the old Wutong community - she wants to find out the truth about her parents' death, she also wants to redeem the person trapped in obsession, and she also wants to live as her own light.
