In the film, Tom's Ethan Hunt is joined by a new IMF team (Jeremy Renner, Paula Patton and Simon Pegg) as they face their most impossible mission yet. After the Kremlin is destroyed, the IMF is implicated in a global terrorist bombing plot and shut down. "Ghost Protocol" is initiated, meaning that Hunt and his rogue team must go undercover -- completely off the grid with no help from the U.S. government -- to clear their organization's name and track down the real terrorists out to incite global nuclear war.

At some point, the plan calls for Tom's character to climb the world's tallest building in Dubai, which Tom did himself. The Burj Khalifa stands at over 2,716.5 feet tall and you can see every inch of it in our new video.

The movie, which opens December 21, will also be shown in IMAX theaters.
