When Agent Ethan Hunt takes holiday on a rock climbing expedition, he is rudely interrupted by a pair of missile- launched, self-destructing designer sunglasses encoded with instructions for his latest mission. It seems Biocyte Pharmaceuticals is missing Chimera, a skin-corroding virus that was manufactured to boost sales of their newly developed super-strength antiviral formula. Unfortunately it has fallen into the hands of Sean Ambrose, a business- minded MIF traitor with a thirst for stock options. Once the public learns that Chimera will melt the flesh off their bones within 27 hours of injection, the price of Biocyte's antidote will skyrocket. Can Ethan Hunt stop him before he takes over Biocyte and infects the city of Sidney?
