Vesper Lynd (Eva Green) works for the Financial Action Task Force of Her Majesty’s Treasury and has experience in illicit banking practices. She supervises the British government’s funds that finance Bond in a high stakes poker tournament organized by Le Chiffre. During the game she helps Bond overcome a Ugandan Warlord and saves Bond’s life when he is poisoned.
Vesper is kidnapped by Le Chiffre to lure Bond into a trap in order to extort the tournament winnings. Vesper makes a deal with Mr. White to spare Bond’s life in return for the funds. Before she can transfer the funds to Mr. White’s accomplice Gettler, Bond confesses his love for her and resigns from MI6.
In Venice, Bond uncovers Vesper’s deception. Although he kills her enemies, Vesper cannot live with her actions and she locks herself in the elevator of a collapsing building and drowns. Bond is devastated by her death and closes himself off emotionally.
Vesper leaves Bond an essential clue to help him trace the terrorist network – on her mobile, she stores Mr. White’s number.
