Harper's Island debuts tonight; here's a sneak peek

CBS has posted a teaser for its new horror mystery series Harper's Island, which debuts tonight. You can watch it after the jump.

Christopher Gorham (Jake 2.0) stars as Henry, a man whose friends and family gather together on the title island for his wedding to high-school sweetheart Trish (Katie Cassidy). It's far from a joyous homecoming for many, as seven years ago someone killed several people on the island, including the mother of Henry's best friend, Abby (Elaine Cassidy), who reluctantly agrees to return to the island for Henry's nuptials. Worse, someone starts killing members of the wedding party.

Harper's Island debuts tonight and will air Thursdays at 10 p.m. ET/PT.
