Su Xiaoman's eldest sister flees from her wedding. To save her gravely ill father, younger sister Su Xiaoman is forced to take her place in marriage to Zhao Tiezhu, an idiot despised by everyone. Unexpectedly, the idiot turns out to be a victim enduring three years of humiliation while pretending to be a fool for revenge. Step-mother Zhao Cuilan's vile acts—colluding with village officials to commit evil, imprisoning and harming mothers, corruption, and seeking personal gain—are all fully exposed. Su Xiaoman unexpectedly uncovers the mystery of her own identity, joins hands with Zhao Tiezhu to gather solid evidence, overthrows various black and evil forces, clears her grievances, reclaims her family property, and establishes a women's cooperative to lead the women of the entire village to self-reliance and strength, ultimately welcoming a fulfilled and reborn life.
