The deep-cover espionage agency known as the IMF has been under fire, but now it faces total disbandment, even as the most harrowing threat yet known to the free world lies in the shadows. That threat is The Syndicate, an impenetrable, exquisitely-trained group of renegade spies who have left behind their countries for an agenda all their own - an agenda intent on destabilising the very foundations of civilisation. The Syndicate has long been rumored to be just a wild-eyed myth among spies. But Ethan Hunt has just uncovered the unwelcome reality that this rogue nation is not only real but a ticking time bomb about to detonate worldwide if he doesn't act. The CIA doesn't buy it. His own team is under threat. Yet, Ethan will never turn his back on the highest stakes.
