Phoenix Wallace, in her past life, favored younger son Jay Leighton, who abandoned her. Elder son Gordon Leighton, whom she mistreated, died searching for her; daughter-in-law Rose also died. Reborn in 1978, she reverses favoritism, protects Gordon's family, and punishes Jay. She starts a business with Rose, supports Gordon to become Provincial Science Champion, buys a house, builds a factory, and leads the family to a successful comeback.
