Riverrun (1968)

A young unmarried couple leave the politically turbulent Berkeley behind for a life in the country. Finding a place in sheep country, the couple awaits the birth of their first child as they revel in bucolic splendor. The tensions of city life are left behind as things progress towards the anticipated due date. The couple wishes to have a natural childbirth and are comforted that the expectant father is a pre-med student with some knowledge of the upcoming situation. Things go along smoothly until the expectant mother’s father returns after years of being a sailor.
