Lu Tiancheng accidentally wins seven million in the lottery, but gives all the huge sum to his daughter Lu Xuerou, treating his son who meticulously cares for him with all kinds of harshness, which draws condemnation from the whole internet. He actively starts a five-day whole-network live stream, letting the public accuse him of being biased and ruthless. The live stream process is full of twists and turns, with the seemingly filial son, the spoiled and money-worshipping daughter, and the daughter-in-law who protects her husband everywhere staging scene after scene of family farce. As the live stream progresses, the truth slowly surfaces. It turns out that today's "son" is actually an adulterer disguised through plastic surgery, and the real son had long ago met a tragic end. Lu Tiancheng endures and lays out a plan, while his daughter cooperates in disguise to collect evidence, finally exposing the conspiracy in the spotlight.
