mission Impossible

In Sydney, bio-genetics scientist Doctor Vladimir Nekhorvich sends a message to the IMF for Dimitri (Ethan Hunt's cover name), his old friend, warning that his employer, Biocyte Pharmaceuticals, forced him to develop a biological weapon, the Chimera virus, to profit from the cure, Bellerophon. He injects himself with the virus, carrying Bellerophon in a bag. However, en route to Atlanta, IMF agent Sean Ambrose, who was disguised as Dimitri, goes rogue, betrays Nekhorvich, using sleeping gas on everyone aboard, steals Bellerophon, and jumps out of the plane just before it crashes into the Rockies.
