Harper's Island is an American horror mystery limited series created by Ari Schlossberg for CBS.

The plot follows a group of family and friends that travel to the titular locale for a destination wedding, only to learn that there is a killer among them.

At the center of the mystery is Abby Mills (Elaine Cassidy), whose mother was one of several people murdered by John Wakefield seven years prior.

After 7 years, Abby is finally returning to the island for her best friend Henry's wedding, but now the killing starts again and everyone is a suspect.

In May 2008, the show was retooled, with Jeffrey Bell coming on board as showrunner and Jon Turteltaub as an executive producer.

During the retooling process, six of the pilot presentation's fifteen original cast members were replaced, including Ryan Merriman (Henry Dunn), Samantha Noble (Trish Wellington), Bill Dow (Sheriff Mills) and Bill Pullman (Uncle Marty).

Thomason, Matt Barr, Cassandra Sawtell, Brandon Jay McLaren, Chris Gauthier and Sean Rogerson.

When she does, Sheriff Mills explain that Abby's mother used to date Wakefield until he got violent with her, and she ran away to the island to get away from him.

Despite falling ratings, CBS aired all Harper's Island episodes, although the show was moved from its original night and time to Saturdays.
