BANG! A gunshot rings out. A man slumps forward and falls face-first into the sand. Guests at a huge party at nearby Grayson Manor enjoy the fireworks fill the sky of this Labor Day weekend night. It’s an engagement bash for Emily Thorne (Emily VanCamp) and Daniel Grayson (Josh Bowman). The only problem is the prospective groom is nowhere to be found.

Daniel’s disappearance does not please his mother, Victoria Grayson (Madeleine Stowe), the reigning queen of the Hampton social scene. Her daughter, Charlotte (Christa Allen) and Declan Porter (Connor Paolo) head down to the beach to do a little skinny dipping. Moments before they arrived, Declan’s brother, Jack Porter (Nick Wechsler), pulled a body from the clawing surf. A cell phone call from Emily to her missing fiancé causes Jack to flee.

We jump back five months to when Emily first rents a house belonging to Lydia Davis. As she caresses the two intertwined infinity signs carved on the porch, we see through flashbacks that Emily has been here before as a little girl with her dad. In the past, however, Emily was known as Amanda.
