After John retired, he was selected by the Speaker of the House of Representatives Raphson as his personal bodyguard, but he was not too satisfied with the job. He dreamed of becoming a Secret Service agent to directly protect President Sawyer. His daughter Emily is fascinated by politics because of John's military experience. In order to repair the father-daughter relationship, he took her to the White House for an interview with the Secret Service. In order not to disappoint her daughter by the bad news of the interview failure, he took her to join the White House tour group.
Unexpectedly, during the visit, the White House was occupied by a group of paramilitary organizations equipped with heavy ordnance, and the president was in a crisis of being hijacked. While rescuing from the outside world, as a failed agent, John can only rescue the president and resolve the national crisis alone; as a father, John must also ensure that his beloved daughter escapes safely. In the course of the action, John joined forces with his superiors inside and outside, and also fought side by side with the savvy President.
