Zhang Yu, an honest and hardworking man, spends all his savings helping his younger brother, Zhang Tao, purchase an RV and even takes responsibility for the loan. Unexpectedly, his brother takes advantage of his marriage into his wife's family to seize the vehicle, while the rest of the family treats Zhang Yu unfairly and blames him. Zhang Tao and his wife become increasingly resentful, openly twisting the facts and spreading false rumors. They go so far as to smear Zhang Yu's background, fabricate stories, and viciously defame him, subjecting him to widespread criticism and driving him to the brink of despair. Fortunately, with the wholehearted support of his wife and parents-in-law, Zhang Yu gathers all the evidence and makes it public, completely turning public opinion in his favor. The two wrongdoers eventually suffer the consequences of their actions and are punished by law. Zhang Yu finally cuts ties with his cold and selfish birth family and embraces a peaceful new life with the family members who genuinely care for him.
