The search for the killer becomes the obsession of his life. Knowing that this is not the first such killing in the region and one of the suspects rolls with a big American car, he opened a gas station. In addition, he befriended a woman who has a little girl to use it as bait. Does it prove that public opinion and apparent sound reason was wrong? He found the real culprit and he will keep his promise?
That is the subject of this fascinating thriller, based on an original screenplay by the author (who is a little different this novel). The film was directed by Ladislao Vajda (`It happened in broad daylight '). For cons, the film Sean Penn 'The Pledge' is based on the same novel.
Highly recommended reading.
