Cassinelli is Commissioner Matteo Rolandi, Killer Cop! While on a routine narcotics detail in a high-class motel, a bomb explodes killing several delegates and important politicians that were attending a summit. Seen as an act of terrorism perpetrated by rebels, the officials put Judge Arthur Kennedy on the case since he has no known political leanings. When Matteo's best friend and fellow officer gets a lead on the bomber, and is killed for it, our hero goes into Killer Cop mode… even after being told to stay off the case. Despite the warnings from officials (Not to mention the witnesses being killed one by one!) Matteo seems to stay one step ahead of everyone else, that is, until he gets too close to the truth! Corruption, assassinations, and deadly killers seem to be in every aspect of the case not to mention several plot twists, secret agendas and double agents playing both sides! This is one very cynical Italian crime thriller that should not be missed by aficionados of the genre. Luciano Ercoli's pessimistic direction, along with Stelvio Cipriani's incredible soundtrack, help create a very dark and sinister atmosphere with a powerful message about the mixing of crime, power, and politics.
