During the famine years, young widow Wren Linton is driven out of her home by her cruel brother-in-law. She accidentally adopts three adorable children with special abilities: Bonnie Linton, a baby with extreme good luck, Todd Linton, who is born with superhuman strength, and Maeve Linton, who has a jinx ability. With Bonnie's lucky streaks, Todd's strength to protect the family, and Maeve's jinx power, Wren goes from foraging for wild vegetables to opening the Three Treasures Restaurant. She outwits greedy shopkeepers and corrupt officials, promotes potato cultivation to save the local people, is eventually awarded the title of First-Class Grace Madam, and leads her family and fellow villagers out of the famine.
