A New Look for Network Horror – “Harper’s Island” is a new suspence horror series for network television. It will make its debut on CBS beginning April 9, 2009 at 10 ET.

The show, which has been approved as a 13 episode macro-series by CBS, surrounds a group of family and friends who have traveled together on a boat to a secluded island off the coast of Seattle for the latest in marriage crazes — a destination wedding.

This particular island has a history for being the famous locale for a streak of unsolved murders that occured seven years earlier. Although they’ve come to laugh and to love, what they don’t know is they’ve also come… to die. As the wedding festivities begin, friendships are tested and secrets exposed as a murderer claims victims, one by one, transforming the wedding week of fun and celebration into a terrifying struggle for survival.

In every episode, someone is killed and every person is a suspect, from the wedding party to the island locals. By the end of the 13 episodes, all questions will be answered, the killer will be revealed and only a few will survive.

The macro-series will feature a young and upcoming cast with such actors as Matt Barr (”One Tree Hill”), Elaine Cassidy (”The Ghost Squad”), Katie Cassidy, daughter of the famous singer/actor David Cassidy and one of the stars featured on the CW hit series “Supernatural,” as well as veteran actors like Jim Beaver (”Deadwood,” “Supernatural”) and Richard Burgi (”Firefly,” “Desperate Housewives”).

Even the actors didn’t know until they got the script for each new episode if their character would be killed or survive that week, making the intrique for their camera time even that much more interesting.” – SOURCE
