CHERYL LADD as Dr. Dawn Holliday Cheryl Ladd portrays Dr. Dawn "Holli" Holliday. A brilliant forensic scientist, she inhabits the high-tech world of our rapidly approaching future -- a place where hot button terms like "DNA," "DQ-Alpha typing," and "polymerase chain reaction" are the currency of the day. A vacation in paradise thrusts Holli into a difficult murder case, and her skill in resolving the mystery makes her the one and only candidate to become the new Medical Examiner for the state of Hawaii. Even a seemingly perfect job in a perfect place is not without its drawbacks, the principal one being top Honolulu homicide investigator Lt. Mack Wolfe (Richard Burgi). RICHARD BURGI as Lt.

Mack uses his tongue-in-cheek humor to insulate himself from the ugly realities of his job. A veteran of several failed relationships, including two marriages, he is nonetheless intrigued by the arrival of the beautiful and brainy new medical examiner, Dr. Dawn Holliday (Cheryl Ladd). PAUL GLEASON as Captain Dave Herzog Paul Gleason portrays Captain Dave Herzog, a by-the-book cop who has to keep his friend, Mack Wolfe (Richard Burgi) out of trouble.
