Outcast by his co-workers and living alone, Koistinen is a security guard who works the night shift in a luxury shopping mall in Helsinki. But when icy blonde Mirja approaches him, the lonely Koistinen falls helplessly for her, unaware she is manipulating him for her criminal boyfriend.
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.
