In the gritty backdrops of New York City, a serial killer is on the loose, targeting young women and murdering them in gruesome, brutal ways. The city is gripped with fear as each victim falls, with the killer mocking the police by calling them and taunting them with a bizarre, duck-like voice. The seemingly deranged criminal employs a disturbing mix of violence and sadism, casting a shadow of terror over the streets. With the public in panic and the media sensationalizing the murders, the pressure mounts to catch the psychopath.

Lieutenant Fred Williams, a weary and tough New York detective, is tasked with the challenging pursuit to track down and apprehend the murderer. Teaming up with a college student named Fay Majors, who may have narrowly escaped the killer's grip, the two delve into a twisted world that lies beneath the city's façade. As they investigate through the decrepit corners of New York and connect the dots between the vicious killings, the duo discovers that the identity of the killer is as unpredictable as his motives, and the case grows increasingly complex. Hindered by the lack of substantial leads and the killer's cunning ability to evade capture, Williams and Majors race against time to prevent the next death in an escalating series of horrors.
