Two years later, UK Prime Minister James Wilson suddenly dies, and arrangements are made for the Western world leaders to attend his funeral in London. Secret Service Director Lynne Jacobs (Angela Bassett) assigns agent Mike Banning (Gerard Butler), a close friend of US President Benjamin Asher (Aaron Eckhart), to lead Asher's security detail while overseas, even though Banning's wife Leah (Radha Mitchell) is due to give birth to their child in a few weeks. The entourage arrives via Air Force One at Stansted Airport, and Banning pushes their arrival at the Somerset House in London via Marine One earlier. As Asher's Presidential State Car arrives at St Paul's Cathedral, a series of coordinated attacks by terrorists disguised as London Metropolitan Police, the Queen's Guardsmen, and other first responders erupts, killing the other Western leaders, damaging or destroying major landmarks and generating mass panic. Asher's early arrival has thrown the attack on him at St. Paul's off-guard, and Banning is able to rescue Asher and Jacobs and rushes them back to Marine One. As the helicopter and its escorts takes off, terrorists fire Stinger missiles at them, destroying the escorts and forcing the damaged helicopter to crash-land in Hyde Park. Banning and Asher suffer only minor wounds, but Jacobs is fatally injured, and she makes Banning promise to get back at whomever did this. Banning quickly escorts Asher into the London Underground as the city's power is lost and people take shelter in their homes.
