John Cale (Channing Tatum) was turned down after his interview with the Secret Service, and doesn't know how to break the news to his daughter, who is also on a White House tour with him when a mercenary group takes over the White House. Because he is there and caught in the middle, it is now up to Cale to rescue both his daughter and President Sawyer (Jamie Foxx).
The story is pretty well written, with a couple of unexpected twists making it more than just an action movie.
The last 20 or 30 minutes puts a somewhat negative end to it, with too many explosions and a very implausible scene with someone waving off an Air Force mission by waving a flag.
It was pretty entertaining for an action movie, but the ending could have been better.
