The first couple is on full alert, deflecting new threats from near and far…

Lieutenant Sam Holland has seen just about everything as a D.C. homicide detective, but she’s never been asked to lie to her closest colleagues and her husband—until now. With national security on the line, Sam makes a deal with the devil that quickly comes back to haunt her as she assists in a baffling case that leads right back to the Oval Office, where her husband is mourning the loss of his trusted aide, Navy Lieutenant Juan Rodriguez.

For President Nick Cappuano, the betrayal cuts deep. The military advisers he inherited from the Nelson administration plotted to remove him from office, and now, the young man who warned him of their deceit is dead. But nothing is as it appears, and with the NCIS building a case against the disgraced Joint Chiefs, Nick is forced to carry on with the duties of his office while wondering who’s coming for him next.

Sam no sooner gets one situation under control when another murder victim requires her full attention. A woman tied to an earlier cold case is found dead in her home in a case that’ll have Sam and her team digging deep into the past to find a ruthless killer while wondering if they should be looking much closer to home for the person who wanted her dead.

As if they didn’t have enough to worry about, a new threat to their happy family has them considering drastic measures to protect the ones they love the most. While storms rage all around them, Sam and Nick take refuge in each other and find the strength they need to carry on.
