Cage plays Keith, the big bad guy who does nothing wrong, who is arrogant and arrogant, and is only good to his only younger brother, Polisei, and usually bends down to tie Poli's shoelaces.
John Travolta plays Sean, a cop whose children have been hunted down for years after Keith's children were killed by Keith.
On this day, Keith placed an amazingly powerful timed bullet in the city, and when he was about to leave by plane, he was rushed to the airport by Sean to intercept and arrest him, which was a happy thing, but because of the bullet, the crowd needed to continue to follow up on the case. The police can't do anything about the Keys brothers, and in desperation, the police team figures out shawn and Keith swap faces, and then Shaun goes to Polly to defraud the location and password of the bullet.
After changing his face, Sean successfully obtains the password and location, but at this time Keith wakes up in the hospital and holds The Doctor hostage to stick Sean's face to himself, so that the identities of Shaun Keith and the two are reversed.
Insiders are killed, the real prisoners are hanging out in their own identities, and how should Shaun, who is in a desperate situation, treat himself.
The whole plot is reasonable and compact, the action scenes are exciting, and friends who like action feature films can watch it.
