Policistu Johnu Calu iz Washingtona ni uspelo dobiti sanjske službe. Postati je želel agent tajne službe, v kateri bi varoval ameriškega predsednika Jamesa Sawyerja. Ker noče razočarati hčerke s slabo novico, jo odpelje na turistični ogled Bele hiše. Predsedniško rezidenco med njunim obiskom zavzame močno oborožena paravojaška skupina. Ameriška vlada se pogreza v kaos in čas se izteka, prav Cale pa je tisti, ki bo moral z lastno iznajdljivostjo in spretnostjo rešiti svojo hčer, predsednika in vso državo.
Capitol Policeman John Cale has just been denied his dream job with the Secret Service of protecting President James Sawyer. Not wanting to let down his little girl with the news, he takes her on a tour of the White House, when the complex is overtaken by a heavily armed paramilitary group. Now, with the nation's government falling into chaos and time running out, it's up to Cale to save the president, his daughter, and the country.
