If you had to kill three people to save your best friend's life, would you do it?
When John Rain decides to get out of the business, his hand is forced by rogue CIA operative Jim Hilger. Hilger kidnaps Dox, Rain's trusted partner and closest friend, and offers Rain a choice: carry out a final assignment, or bear the responsibility for Dox's murder.
For a professional like John Rain, the choice ought to be easy: Do the job-a series of three hits-then walk away. But how does Rain know Jim Hilger won't kill Dox anyway, once the assignment is complete? How does he know that each of the hits isn't simultaneously a setup for Rain himself? And what will he do when he finds out that among the targets of this lethal game of extortion is someone else Rain cares about deeply?
From the urban canyons of Silicon Valley and New York to the lush forests of Bali, the boulevards of Paris, and the old killing fields of Vietnam, Rain must grapple with his age, his enemies, and most of all, his conscience in a battle that not even Rain-"the stuff great characters are made of" (Entertainment Weekly)-can hope to survive intact.
