Washington, D.C. Police Lieutenant Sam Holland and her husband, U.S. Senator Nick Cappuano, have been looking forward to a quiet Thanksgiving with their son. But any thoughts of a restful holiday are dashed when Sam and Nick return home to a gruesome scene: her seventeen-year-old niece Brooke, barely conscious and covered in blood on their front stoop. With lines between personal and professional blurring in this emotionally charged, deeply personal case, Sam is relying on Nick more than ever for support. But when suspicious images from the night in question appear on social media, Sam begins to wonder if her niece is telling her everything she knows about what really happened. And when Nick questions her tactics-and her ethics-as she races against the clock, Sam will need to decide how far she's willing to go to prove Brooke is a victim, not a murderer.
