Chen Mo was once a talented fisherman. He retired due to an accident seven years ago and became the owner of a small town fishing gear shop. Technology dominates fishing competitions, data and equipment are king, and natural intuition is abandoned. The national team was in crisis, and he was forced to return, facing doubts, conspiracies and past injuries. Relying on his instinctive perception of water, he swam upstream, exposed sponsors, and shattered technological superstitions. He searched for fish traces in the wind and rain of Qiandao Lake, struggled with his will in the huge waves of the fjord, and finally reconciled with the sea among the raging waves of the Southern Ocean. He cut the fishing line and let go of the giant thing. He did not compete for the championship, but only kept his original intention. After ten years of fishing, what he regained was not his honor, but the most primitive contract between man and nature.
