When a plane crash carrying Dutch's wife Peton and Kay's husband Cullen crashes into Chesapeake Bay, leaving no survivors, it marks just the beginning of a mystery that will not only lead Dutch and Kay to disturbing and shocking information about their spouses, but bring these strangers together in an unlikely romance.
