Qiangzi accidentally picked up a glowing scale while fishing by the river and discovered that it could bring good luck. As long as he held the scale in his hand, the fish would take the bait one after another. However, behind this "good luck" are hidden strangeness and crisis. Chickens and fishes are dying in the house, black shadows appear at night, mucus is everywhere, and strange things happen frequently. Despite repeated dissuasion from his family and friends, Lao Wu still insisted on leaving his scales and was determined to uncover the truth. In several battles with the "water monster", he gradually discovered that things were not simple.
