One of the victims was the sheriff's wife. After her death, Sheriff Mills sends their daughter, Abby, to live with family in LA and she hasn't returned since. 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.
