MI6 agent James Bond arrives at a Swiss bank in Bilbao, Spain, to retrieve money for British oil tycoon Sir Robert King. Bond also wants the name of the killer of a fellow MI6 agent, but the banker is killed by his assistant before he can reveal it. Bond escapes from the banker's office with the money, but it is revealed to be booby-trapped; Sir Robert is killed by an explosion inside MI6 headquarters in London. Bond gives chase to the assassin on a Q-modified speedboat down the Thames to the Millennium Dome, where she attempts to escape by hot air balloon. Bond offers her protection, but she refuses and blows up the balloon, killing herself.
