Lu Zheng, owner of a cold chain company, arranges for his brother-in-law, Song Dapeng, to join the company. Greedy and arrogant, Dapeng shuts down the system without authorization to save on electricity, causing millions of yuan in goods to be damaged. His sister, Song Yaqin, repeatedly covers for him, even forcing veteran employees to take the blame and embezzling company funds to pay off her brother's debts. Facing customer accountability and pressure from his parents-in-law, Lu Zheng gradually uncovers the truth. When a typhoon strikes, Dapeng tampers with the backup equipment again to save on fuel, triggering a second crisis. As evidence comes to light and the siblings blame each other, the protective umbrella of the so-called "family" finally shatters, and Lu Zheng resolves to make everyone pay the price they deserve.
