Staying on an isolated beach in the Bahamas, the Mastersons meet William (Stephen Lang) and Mary (Claudia Church), who live on a nearby island and invite them for dinner. Upon their return, Lydia and Creighton are shocked to discover that they have been robbed. With no sign of the intruders, they seek help from the only other people on the island, a couple named Max (Dominic Purcell) and Nina (Marie Avgeropoulos). Though friendly at first, the mysterious couple seems to be hiding darker motives. With no one to trust but each other, Lydia and Creighton find themselves in a fight, not only to get off the island but for their lives!
