Colpo alla nuca

During the ethnic parades on Fifth Avenue, two plainclothes policemen died: the first during the parade of Poles in America, the second during Columbus Day, dedicated to the Italian community. The two were dating outside of the service, with three other colleagues. Meanwhile, a young man, psychologically unstable, wanders among the parades, among the cheering crowds. A recurring dream disturbs him: him dressed as a woman killing a policeman in the city underground. And it's already the day of the Spanish parade... After the two officers killed during the Polish and Italian parades, in New York a third policeman is killed during the Spanish community celebration. Suspicions are directed towards a boy who had a terrible experience as a child: his father, a policeman, mistreated him and his mother, no longer able to bear that daily drama, killed her violent husband. The boy under investigation has disappeared and, during the big Halloween parade, a fourth agent is murdered with a shot to the back of the head. Only the discovery of the boy's body sheds a new, sinister light on the case...
