Dutch Van Den Broeck, a sergeant in the Internal Affairs Division of the Washington, D.C. police department, and Kay Chandler, a New Hampshire congresswoman running for re-election, know about trust. Their careers depend on it. Their marriages are founded on it. Or so they thought. When an airplane carrying Dutch's wife Peyton and Kay's husband Cullen crashes into the 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.
