"Dead Drop is the explosive, action-packed story of Michael, a former CIA covert operative on a personal journey of revenge to find the man who he believes tried to kill him: his best friend. After being shot, pushed out of a plane, and miraculously surviving a dead-drop from 5,000 feet, Michael awakes to a living nightmare. His memory is limited, and psychotic tendencies have begun to creep in. Defying the orders of his CIA handlers, Michael re-inserts himself into the dangerous Mexican smuggling ring where he was operating deep under cover. He snakes his way through the underbelly of Northern Mexico, hunting for Santiago, the boss of the smuggling cartel that Michael believes threw him out of the plane - and who is holding his girlfriend hostage."
