Top financial group chairperson Wang Xiue disguises herself as a cleaner to test her daughter, but is looked down upon and bullied by the deadbeat Zhang Yuan and his family. She exposes the conspiracy on the spot and cleans house, only to be instigated by the deadbeat when the president's daughter causes a scene at the villa. Wang Xiue reveals her true identity to severely punish the villains, strips the president of his position, bans the deadbeat and his mother, and ultimately lets her daughter take over the group, giving the mother and daughter a happy ending.
