Former Army Ranger Mike Banning Gerard Butler is the lead U.S. Secret Service agent assigned to head the U.S. Presidential detail. Banning maintains a personal, friendly relationship with President Benjamin Asher Aaron Eckhart, First Lady Margaret Ashley Judd and their son Connor Finley Jacobsen. During a snowy Christmas evening drive from Camp David to a campaign fundraiser, the car transporting the First Family spins out of control on a bridge due to icy conditions; Banning pulls Asher from the vehicle, but Margaret falls to her death while inside the car. Eighteen months later, having been removed from the presidential detail, Banning works at Treasury headquarters. During a meeting between Asher and South Korean Prime Minister Lee TaeWoo Keong Sim, a North Korean terrorist organization, led by Kang Yeonsak Rick Yune, mounts an air and ground assault that results in the capture of the White House. The group is aided by treasonous members of the prime ministers own detail, including Dave Forbes Dylan McDermott, a former Secret Service agent. Asher and several top officials are held hostage in the White House bunker; South Korean Prime Minister Lee is executed on live video. Before his own death, detail agent Roma Cole Hauser alerts the Director of the Secret Service Lynne Jacobs Angela Bassett that Olympus has fallen. Kang seeks to use Ashers hostage status as leverage to force U.S. officials to withdraw the Seventh Fleet and U.S. forces from the Korean Peninsula, thus removing American opposition to a North Korean invasion of South Korea. He also seeks to destroy the American nuclear weapons stockpile by detonating them in their respective silos across the country, turning the United States into an irradiated wasteland. To accomplish this, he requires the access codes to a system called Cerberus, which are held by three top government officials, including the President, all of whom are inside the bunker. Asher orders the other two officials to reveal their codes to save their lives, certain that he will not give up his code. During the initial assault by Kangs forces, Banning joins the White Houses defenders. He falls back into the White House, disabling the internal surveillance and gaining access to Ashers satellite ear phone, which he uses to maintain contact with Jacobs and Speaker of the House Allan Trumbull Morgan Freeman, now the Acting President. Authorized to proceed, Banning’s first act is to save the Presidents son Connor, whom Kang plans to use to force Asher to reveal his Cerberus code. Banning finds Connor hiding in the buildings walls and sneaks the boy to safety. Banning then begins reconnaissance, during which he kills several of the terrorists, including Forbes. Meanwhile, Army Chief of Staff General Edward Clegg Robert Forster convinces Trumbull to order an aerial SEAL assault on the White House. Kang discovers the assault force and activates the Hydra 6, an advanced antiaircraft system built by the military. Discovering the system, Banning advises Trumbull and Clegg to abort the mission, but the new weapon system annihilates most of the assault force before Banning can stop it. Kang retaliates for the infiltration by killing Vice President Charlie Rodriguez Phil Austin. After Banning disables Kang’s communications, Kang tries to execute Secretary of Defense Ruth McMillan Melissa Leo outside the White House in front of the media, but Banning rescues her. With his forces dwindling, Kang fakes his and Ashers death by sacrificing several of his men and the remaining hostages. However, Banning sees through the ruse. Kang eventually cracks Asher’s code using bruteforce attack and activates Cerberus. As Kang and his remaining men attempt to escape, Banning ambushes them and kills the remaining terrorists. During the fight, Asher tries to break free from Kangs grip and is subsequently shot by him in the stomach. Banning and Kang confront each other and a climactic fight breaks out, in which Kang quickly gains the upper hand. Eventually, Banning kills Kang by stabbing him in the head with a knife and disables Cerberus with the assistance of Trumbull and his staff, with only seconds to spare. During daybreak, Banning walks out with Asher and is received by the soldiers posted to await their arrival. After the events, the United States begins to heal from the attack, while Banning once again heads the presidents security detail.
