Newlyweds Molly and David are only sixteen and eighteen years old when they pack up their wagon and head west across the plains in search of a new homestead. At first their new life is full of promise: The wheat is high, the dugout is warm and cozy, and a new baby is born to share in their happiness. Then disaster strikes, and David must go east for the winter to find work. Molly is left alone with the baby -- with nothing but her own courage to face the dangers of the harsh prairie winter.
