chunk: FBI Special Agent Sean Archer (John Travolta) survives an assassination attempt by freelance domestic terrorist and homicidal psychopath Castor Troy (Nicolas Cage), but the bullet pierces through Archer's chest and hits his son Michael, killing the boy.
  Six years later, Archer's vendetta against Castor culminates in his team's ambush of Troy and his younger brother/accomplice Pollux (Alessandro Nivola) at Los Angeles International Airport. Castor goads Archer with knowledge of a bomb located somewhere in the city set to go off in a few days, but he is knocked into a coma before Archer can learn more.
