About the title
In the world of professional assassins there is a ranking of their own, and at the top of it is someone known as Gunther. No one knows what he looks like or where to find him, but it's absolutely certain that he's better left alone. Hitman Blake decides to set the hierarchy straight and destroy the legendary Gunther at any cost, assembling a team of mercenaries from around the world: a hacker, a demolitions expert, a terrorist's daughter, a pair of reckless twins from Russia, a Chinese poison specialist, and even an assassin with a bionic arm.
