Shrapnel from an explosion tore up Jackson's leg and ended his career as a Navy SEAL. Being forced into the civilian world was bad enough, but being told he's crazy is intolerable. No matter what the doctors or anyone else tells him, he knows a supposed ally was responsible for his injury, and that same man is determined to shut Jackson up for good.

When Jackson sees a kayaker clinging to his boat from the balcony of his beach house, his instincts tell him something dire is about to happen. Jackson rescues the injured man and insists on hiding him until a former SEAL teammate arrives. As Jackson struggles with separating reality from soul-shattering flashbacks, the injured man's compassion and growing trust tear down his barriers, and Jackson begins to wonder if his heart is as dead as he'd assumed.
