John Creasy (Denzel Washington), a former CIA counterinsurgency and counter-terrorism operative but is now uninterested and disillusioned with life as a result of all the deaths and destruction he had witnessed and all the things he had done in the past.
He gets a job as a bodyguard in Mexico, and is in charge of protecting Lupita Ramos, the little child of a rich Mexican businessman. He gets to like Lupita because the little girl gave him a reason to live again. Lupita is kidnapped and Creasy is seriously injured while trying to protect her.
She is subsequently "killed" when the money intended for the kidnappers was snatched by unknown persons.
Bereaved and seeking vengeance, John Creasy is out to kill every single person responsible for the kidnap and killing of Lupita Ramos. But this might involve a bunch of very powerful corrupt Mexican police officers and even going a head on confrontation against organized crime.
But John Creasy does not give a damn, he is on fire.
