Very good movie. You know you are reading, or watching, a very good story, when the story refers to people from another place, country, continent, and/or culture, where what happens is closely related to their particular environment, and yet, it touches you because what the story says it is also very much applicable to yourself, your situation, your place, your country, your continent, and your culture.
The main points of the movie are: 1) You do not need to be behind bars in order to live in a prison. In fact, at some point it becomes evident that most of the main characters are safer in prison than outside. Their lives are certainly more at risk travelling through the country than behind bars.
2) Sometimes you do what society tells you you have to do, even when nobody will be better off. This is particularly evident about the end of the movie (spoiler alert), when one of the main characters, upon learning of the death of his brother, tells the widow "I am now your husband; it is the code", even though he has his eyes on another woman in the village, that other woman likes him, he does not want to be the husband of his sister in law, and the widow and her children do not want him to become husband and father. But "it is the code", and that suffices. As when at the beginning one of the characters is out during a curfew that he did not know it was in effect, and is detained. Everybody understands his predicament, but the law says he has to be detained, and so he is. In another story, a man has to kill his unfaithful wife, even though he does not want to.
This is a must see. This films will describe not just what was happening in Turkey 30 years ago, but what is happening everywhere today, in one way or another. It is about living in a prison, even though you are supposedly a free citizen.
