And there's going to be online content also:
HARPER'S ISLAND is about a group of family and friends who travel to a secluded island off the coast of Seattle for a destination wedding. This island is famous for a streak of unsolved murders from seven years ago. 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.
Don't miss the broadcast premiere of HARPER'S ISLAND on Thursday, April 9 (10:00-11:00 PM, ET/PT).
Prior to the premiere of the primetime series, CBS and EQAL will launch HARPER'S GLOBE (http://www.harpersglobe.com/) online with original social show episodes that will be complementary to the television storyline with overlapping characters, locations and plots that will continue to evolve throughout the first season of the television show. ...
Representatives from CBS Entertainment, CBS Paramount Network Television, CBS Interactive, as well as writing teams from the show and EQAL, have been working in close collaboration since the series was at the script level last spring to ensure the on air, online and on mobile narratives are cohesive and complementary across all mediums. The online social show will launch on Wednesday, March 18, several weeks prior to the broadcast premiere....
"It's not a pre-requisite to go online in order to follow the series on-air, but those who do will have an authentic entertainment experience that drills deeper into the mythology and mystery happening on HARPER'S ISLAND," said Nancy Tellem, President, CBS Paramount Network Television Entertainment Group.
Well, I think this is the first show I've heard of that is advertising it's end date (July 2nd) as well as it's start date. I'm somewhat interested in it only because Christopher Gorham is in the cast (as the groom, I believe) and I miss Henry from Ugly Betty.
