So Big (1924)

After graduating from a fashionable finishing school and touring Europe with her father, Selina Peake returns to the United States, where her father is accidentally killed after losing his fortune in a gambling den. Selina is reduced to teaching in a high school in the Dutch community at High Prarie near Chicago. She boards in the farmhouse of Klass Poole, a dull-witted market gardener, and finally marries Pervus DeJong, a poor and backward farmer. She shares the drudgery of her husband's futile life and finds happiness only in their small son, Dirk, whom she calls "So-Big."
