Kaya, a fisherman, lives with his wife, Filiz, in a village on the shores of a lake. They have a young daughter, Deniz, who is unable to speak. In search of a cure for Deniz, Filiz decides to try an ancient alternative remedy. She thinks that feeding the girl a breed of fish believed to be medicinal will heal her disorder. The trouble is, the fish is no longer to be found in the village lake. Filiz sets off for another lake to find it. In the end, she catches eight of the rare fish and starts feeding them to her daughter.
When he discovers the fish at home, Kaya has the idea of farming them commercially in the hope of making some money. He asks the faculty staff for advice in how to breed the fish. To set up a fish farm, however, he needs money he doesnt have. And to resolve this, he starts fishing illegally with chemicals. But one day, ambition in using the chemical mix leads him to fatally poison his wife, Filiz, and he ends up in jail for homicide.
