The first female US President Sally Sheridan is shot dead by a sniper during her Veterans Day speech. Her assassin narrowly escapes the scene with his life, national security hot on his heels - or so it seems. Three months later, an elderly couple discover the body of a wounded man in a tree, wearing a parachute. The young man cannot remember the slightest thing about his own identity.
A high-octane suspense drama that centers on Dr. Ellen Sanders, a premier surgeon thrust into a chilling political conspiracy when she and her family are held captive in their home by rogue FBI Agent Duncan Carlisle, a desperate man doing the wrong thing for the right reasons, who orders Dr. Sanders to assassinate the President when she operates on him.
