When a beloved schoolteacher is found murdered in her Neptune, New Jersey apartment in the fall of 2009, suspicion is cast on her soon to be ex-husband. Long after the case goes cold, a detective embarks on a mission to help the man clear his name and track down the real killers.

On February 2, 2010, two masked gunmen commit a violent robbery and shoot Michael Temple Jr., rendering him a quadriplegic for five years before his death. In this unusual cold case, DNA from a knife is used to create a sketch of the killer.
