Sneak peek: 'Harper's Island'

Thomas Wellington has a chat with Hunter Jennings

A group of family and friends travel to a secluded island for a destination wedding. They've come to laugh, to love and, though they don't know it... 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.

"Harper's Island" premieres Thursday, April 9, at 10 p.m. ET/PT on CBS.
