Modern corporate slave Su Muwan accidentally crosses over to a barren and disastrous era, taking over a broken family that is penniless and heavily in debt. The original host was harsh and tyrannical, leaving behind four bullied children and a powerless, honest husband, with the whole family struggling on the verge of starvation year-round. Facing her toxic mother and gambler older brother who engage in endless leeching and extortion, Su Muwan completely breaks away from the original host's ignorance and barbarism, using modern business thinking and decisive courage to forcefully break the deadlock. She tears apart her leeching maiden family, cuts off aggravating family ties, protects her timid and sensitive children, heals her self-effacing and enduring husband, and relies on original snack-making skills to set up a roadside stall and start a business, achieving rapid wealth and leading her whole family out of poverty into a secure home.
