Dr. Mark Sloan is chief of Internal Medicine at Community General Hospital -- and sometime consultant to the local police department. When he's drawn into a case, he combines sleuthing and medicine to solve the crime. That crime is usually one his detective son, Steve, is working on as a member of the local police department. Dr. Sloan's medical colleagues, including doctors Amanda Bentley, Jack Stewart and Jesse Travis, are also frequently drawn into his investigations.

Mark discovers that an impassioned love affair between a nurse and a 17-year-old hospital worker may be the motive for murder.

Mark and Steve find a common thread within three seemingly random murders in the L.A. area and must solve the mystery before a fourth is committed.

Jesse and Susan break down in a small village and are accused of murdering a man whom Susan presumed was killed years ago.

Steve and a tabloid reporter go undercover to find out who has been killing the residents of an idyllic community.
