Movie Face/Off

Obsessed with bringing terrorist Castor Troy to justice, FBI agent Sean Archer tracks down Troy, who has boarded a plane in Los Angeles. After the plane crashes and Troy is severely injured, possibly dead, Archer undergoes surgery to remove his face and replace it with Troy's. As Archer tries to use his disguise to elicit information about a bomb from Troy's brother, Troy awakes from a coma and forces the doctor who performed the surgery to give him Archer's face.
