When a dismembered body is found in New Jersey in 1992, the crime scene poses striking similarities to a murder a year prior; both victims were affluent and closeted men, last seen at a piano bar in Manhattan.

A third victim is part of the queer community's most vulnerable population, sex workers of colour; while the AVP pressures the NYPD and media to connect the murders, another piece of evidence leads investigators to Staten Island.

The clear pattern of a serial killer emerges with a fourth murder, prompting the creation of a multi-jurisdictional task force and the first coverage from national newspapers; an eyewitness leads to a break.

A break in forensic technology leads investigators to a suspect, a nurse living on Staten Island. With their next step being to decipher his past, detectives set out on a quest that takes them back almost 30 years to a murder in Maine.
