When Detective Ashley Taylor and Detective Natalie Simpson are called to the first homicide crime scene in New York City on January 1st, 2000, they figure that they are just getting an early start on the new year. However, the crime scene is nothing like they have ever seen. A well planned murder leads the detective to believe they are dealing with a calculating killer that will strike again. As the time passes, the two detectives discover that there are 54 prior murders with almost the exactly same detail. The only catch is that 27 of the murders are from 1950 and 27 are from 1975. As their body count rises, the two detectives know that they must put together the clues to stop the killer before the 27th victim and the killer goes into hiding for another 25 years. Can the two detectives piece together the clues fast enough to stop a serial killer? A serial killer that could possibly date back 50 years.
