Musta Jää plot
Saara is a gynaecologist in Helsinki. She is elegant, jovial and above all free-spirited. But we don't know what lives under Saara's skin. When you scratch away that self-conscious layer of Saara, you see a revenge-seeking woman. She recently discovered that her husband is having an extramarital affair with a young college student. Her name is Tuuli and she works part-time as a karate instructor. Saara wants to know more about that young woman and she participates in the karate classes. Step by step, she infiltrates - sometimes on purpose, sometimes not - into the life of her rival and a close friendship develops. On the one hand, Saara manipulates her, on the other, she discovers feelings she's never had before. Saara seems to be able to control the situation completely, but the downward spiral turns and Tuuli, Saara and her husband Leo are sucked deeper and deeper into it.
