Tas (Rock) is a film that presents a cross-section of the life of a family living a hard life in the countryside. It is a touch of sadness in the life of people living in nature- even as a part of it. And that life is nothing more than the waiting of a woman and man who lost their son. After waiting for many years, the family tries to get rid of the uncertainty by believing that the wounded man they found at the door is Selim (Ahmet Varli), their son.
