Lu Chuan, who possesses the unique skill of listening to ice and distinguishing fish, is short-changed on profits, squeezed out, and harassed by his own older brother, Lu Tao, before resolutely striking out on his own. Relying on his precise judgment of the icy sea and top-notch fishing skills, he repeatedly creates great achievements in the perilous extreme cold sea. He consistently adheres to the bottom line and integrity of "saving people before saving fish," ultimately winning the respect of peers and foreign-funded enterprises, establishing the Ice Flame fleet, and setting new rules for the ice sea fishery.
