'Family Instinct' is a film about incest - an illegal act, social taboo and a violation of religious norms. Zanda is a 28-year-old woman, worn out by hard work. Surrounded by poverty and despair, she is trying to survive with her two children in a god-forsaken Latvian village. Her hardships can be traced back to living in a relationship with her brother Valdis. When Valdis is put in jail, the local community forces her to make a difficult choice: to stay with him or with her children. Despite her ill fortune, she manages to express her love for the children, still hoping to save her family. The film offers a tragicomic but highly authentic insight into the bleak reality of post-soviet era.
