Lin Tao, an ordinary factory quality inspector, unexpectedly won the lottery prize. Knowing the warmth and warmth of people's hearts, he chose to hide the truth about his sudden wealth and pretended to be ordinary to start a trial of human nature. After returning home, he witnessed the false favoritism of his parents, the snobbery and meanness of his sister-in-law's family, the money-worshipping partner, and the ridicule and bullying of his old classmates. He pretended to be down and out, borrowing money and giving up demolition money, and he screened the sincerity and greed of those around him at all levels. In the end, Lin Tao disclosed his billionaire net worth, slapped everyone who looked down upon him in the face, protected his true family and close friends, and successfully harvested family affection and love with his beloved.
