Hazel Nash wakes up in a hospital and is told she's been in a car accident that killed her father and injured her brother. But she can't remember any of it, because of her own traumatic brain injury. Then a man from the FBI shows up, asking questions about her dad --- and about his connection to the corpse of a man found with an object stuffed into his chest: a priceless book that belonged to Benedict Arnold. Trying to put together the puzzle pieces of her past and present, Hazel needs to figure out who killed this man --- and how the book wound up in his chest.
