Gilbert Grape is a small-town young man with a lot of responsibility. Chief among his concerns are his mother, who is so overweight that she can't leave the house, and his mentally impaired younger brother, Arnie, who has a knack for finding trouble. Settled into a job at a grocery store and an ongoing affair with local woman Betty Carver, Gilbert finally has his life shaken up by the free-spirited Becky.
The four Newton brothers are a poor farmer family in the 1920s. One day, the oldest of them, Willis, realizes that there's no future in the fields and offers his brothers to become bank robbers. Soon the family agrees. They become very famous robbers and execute the greatest train robbery in American history five years later.
