Discovering the murdered body of a young woman in Ramble urban park, New York Assistant DA Alex Cooper and Detective Mike Chapman uncover disturbing links between the savage crime and a string of cold-case disappearances. Alex and Mike race to track down a serial killer before yet another young woman is found dead. Is the body found in the Ramble the first victim of a deranged psychopath, or are other missing women in years past whose remains have never been found connected to this savage attack? Is this enormous urban park a sanctuary in the middle of the city, as it seems to the thousands of New Yorkers and tourists who fill it every day, or is it a hunting ground for a killer with a twisted mind?
