Traveling salesman Flynn Greer sings and plays his guitar at church and catches the eye of Sadie's older sister, Opal. Momma and Caleb don't like Flynn, but Opal has fallen in love and decides to marry the young man if he asks. Meanwhile, Opal and Sadie remind Gerta of her vow of commitment to her new husband, Gabe, when she balks at having to share his father's one-room sod house.
