Henry Silva plays architect(?) David Vannucchi whos young daughter is killed brutally during jewelry heist. Police don't have any clues about the robbers. Vannucchi starts to investigate the case by himself.
Umberto Lenzi directed this vigilante story. Couple of good action scenes, especially the one where thugs destroy Vannucchis car while he and his wife are still inside, but mostly film concentrates Vannucchi's investigations to find the thugs responsible for his daughters death. Ending is pretty good with a small twist. Silva gives a solid performance as a father who is pushed over the edge. Luciana Paluzzi plays Vannucchi's ex-wife.
