Chen Zhiyuan earns 16,000 yuan a month and has handed almost all his income to his wife to support their family for the past eight years, keeping only 800 yuan each month for his fish. But his wife, Fang Jing, cannot even tolerate this little bit of personal freedom. To force him to hand over his salary card, she and her mother pour half a bag of flour into the fish tank left behind by his father. His beloved fish die, and Chen Zhiyuan is utterly heartbroken. He takes back his salary card and stops providing extra financial support to his wife's family. But when he checks eight years of financial records, he discovers that his brother-in-law's car loan, business startup funds, and even his wedding home have all been quietly draining his money. The tank full of dead fish finally exposes the truth this family has hidden for eight years!
