Mission: Impossible - Ghost Protocol

Directed by Brad Bird, the animation director of Superman Story, Andre Namek and Josh Appelbaum are both screenwriters. The film, starring Tom Cruise, Jeremy Renner, simon pegg, Josh holloway, Ving Rhames and Paula Patton, was released in North America on February 6th, 1965.

Intelligence Agency (IMF) agents Jane, Trevor Hannawi and computer expert Benji Dunn set out on a mission to find the messenger who passed the nuclear bomb launch code. Unfortunately, however, their task went wrong, and the code fell into the hands of Sabine Moru, a scorpion beauty killer.

Meanwhile, captain Ethan Hunt (Tom Cruise) escapes from Moscow prison. The next task of this group is to sneak into the Kremlin and get information about a key person. This man's code is "cobalt blue" and he tried to buy this set of passwords. Soon, Cobalt Blue discovered the secret actions of Ethan and Bangui, which triggered the Big Bang in Red Square. Fortunately, the two men fled in time, but Ethan found that he and the whole Mission Impossible intelligence agency had become scapegoats, which led the president to launch "Ghost Operation" and completely disband the intelligence agency.

The team later joined a new member, William Brandt (Jeremy Renner), and Ethan also found that for the first time since he left the mission, he worked with a team he was not familiar with. On the surface, Brent looks like an analyst in the office, but in fact he has a more complicated past. As a last resort, Ethan and the new team can only cooperate, and because the mission intelligence agency has been abolished, they have lost any support, but they must wash their shame and complete the task to avoid the nuclear bomb detonating.
