In 1975, Ryszard Kapuściński, a veteran Polish journalist, embarked on a seemingly suicidal road trip into the heart of the Angola's civil war. There, he witnessed once again the dirty reality of war and discovered a sense of helplessness previously unknown to him. Angola changed him forever: it was a reporter who left Poland, but it was a writer who returned.

A man is murdered, but the person responsible avoids being discovered and arrested. A few years later a police inspector suspects he has found evidence in a newly-published book entitled "Amok".
