Chen Chuan and his wife, Lin Xiu, pour all their savings into running a fish pond. Just as their first batch of fish is about to be harvested, Chen Hai, Chen Chuan's own older brother, brings people to steal fish with nets at night and even expects his younger brother to help. After Chen Chuan refuses, Chen Hai joins forces with fishmongers to force prices down, spread rumors, and even secretly shut off the aerators, causing large numbers of fish to die. Faced with their mother's pleas for reconciliation, false testimony, and schemes to manipulate compensation, Chen Chuan refuses to back down any longer. He saves the fish, preserves the evidence, pursues compensation, and protects his business. This time, he will separate family ties from financial accounts and make his older brother tell the truth in public.
