The Well 1992 one on netflix

This very serious drama, based on a true incident, explores the unremitting labor which put a young mother living in rural isolation into the situation of being charged with having thrown her children down a well. Her husband is an unimaginative, work-obsessed man who cannot see that her constant hard work without any support or sympathy from anyone is driving the sensitive woman to consider suicide. When the loutish fellow discovers that his wife and three children are missing, he calls the police, and a manhunt begins. The police discover the oldest boy alive, and find that the mother tried to drown herself, but has survived. The two younger children remained missing.
