Matthias "Matt" Lee Whitlock is the respected Chief of Police of the small Florida Keys town of Banyan Key. Recently separated, Whitlock is currently seeing local resident Ann Merai-Harrison, an old flame from high school whose husband Chris, a former professional quarterback seemingly oblivious to the relationship, abuses her. While taking Ann to the doctor, Matt finds out she has just been diagnosed with terminal cancer. Matt is also going through a divorce from his wife, homicide detective Alex, and confides in his friend, medical examiner Chae.
