What's the best way to go from number six to number one on the most wanted "10 List"? Assassinating all the world's leaders and creating worldwide chaos is a good start.

In London Has Fallen, secret service agent Mike Banning once again finds himself in the middle of a terrorist plot. This time, the ante is upped when the world's leaders, in London to attend the funeral of the British prime minister, are killed in an explosive attack on the city. When the dust settles, five leaders are dead and one is unaccounted for - the American president. Now, Banning must ensure the safety of President Asher before the terrorists can capture him and execute him as the ultimate propaganda message.
