Watch 007 - Casino Royale Online

In Prague, James Bond corners and kills corrupt MI6 section chief Dryden and, in a brutal fight in a changing room, his underworld contact Fisher, earning his double-O status, which requires two kills. Meanwhile in Uganda, a Mr. White arranges a meeting between a banker, Le Chiffre, and Obanno, the leader of a guerrilla group seeking a safe haven for his funds. Le Chiffre assures the leader that there is "no risk in the portfolio", but his investments actually involve considerable risk: he short sells successful companies and then engineers terrorist attacks to sink their stock values.

In his first mission as Agent 007, Bond pursues an international bomb-maker named Mollaka in Madagascar. After a parkour chase across the city to the Nambutu embassy, Bond kills his target and blows up a part of the embassy to enable his escape. He obtains Mollaka's mobile phone and discovers that it has received an SMS from Alex Dimitrios, an associate of Le Chiffre in the Bahamas. Bond travels there, wins Dimitrios's Aston Martin DB5, and seduces Dimitrios's wife, Solange Dimitrios, who reveals that her husband is flying to Miami on business. Bond follows him to Miami, where he kills Dimitrios, and observes Le Chiffre's henchman, Carlos, leaving for the Miami International Airport. There, Bond foils Le Chiffre's plan to destroy the prototype Skyfleet airliner while managing to kill Carlos, leaving the banker with a major financial loss, since he had shorted and bought put options on Skyfleet stock, which then expired worthless.

Now under pressure to recoup his clients' money, Le Chiffre sets up a high-stakes poker tournament at Casino Royale in Montenegro. Hoping that a defeat would force Le Chiffre to aid the British government in exchange for protection from his creditors, MI6 enters Bond into the tournament. He meets up with Rene Mathis, his ally in Montenegro, and Vesper Lynd, a treasury agent, who is assigned to look after his handling of the government's $10 million buy-in. As the tournament progresses, Bond loses his initial stake and becomes enraged when Vesper refuses to authorise him to buy back in because she considers his play reckless.

Distraught over his failure, Bond prepares to assassinate Le Chiffre when he is intercepted by one of the other players, who introduces himself as CIA officer Felix Leiter, who is also out to get Le Chiffre. Leiter believes Bond has the skill to beat Le Chiffre and offers to supply him with enough funds to re-enter the tournament in exchange for allowing the CIA custody of Le Chiffre. Back in the game, Bond rapidly recoups his losses. When Le Chiffre and his associates attempt to poison him, Bond narrowly survives due to Vesper's intervention. Bond wins the tournament on a straight flush. Following her celebratory dinner with Bond, Vesper is abducted by Le Chiffre, who uses her to lure Bond into a near-fatal car chase and ultimate capture. Le Chiffre tortures Bond for the access code to the game's winnings and when it becomes clear that Bond will not yield, Le Chiffre prepares to castrate him. At that moment Mr. White enters and executes Le Chiffre and his associates for their failure. Bond and Vesper are left alive.

Bond awakens in a hospital on Lake Como and orders the arrest of Mathis, who had been identified by Le Chiffre as a double agent. Bond admits his love for Vesper and vows to quit the service before it strips him of his humanity. Accordingly, he posts his resignation to M and goes on a romantic holiday in Venice with Vesper. However, Bond soon learns that his poker winnings were never deposited into the Treasury's account. Realising that Vesper has stolen them, he pursues her into a building under renovation where she meets members of her organisation. Bond shoots the flotation devices supporting the structure to gain access to the building, but as he does so the foundation starts to slowly collapse into the Grand Canal. After killing the henchmen in the building, Bond finds Vesper imprisoned in an elevator. Apologising to him tearfully, she locks herself inside as the elevator plunges under the rising waters. Bond dives in, breaks into the elevator and pulls Vesper onto the roof of the collapsed building. She dies, despite Bond's attempts to revive her. Mr. White, watching from a balcony, walks away with the money.

M tells Bond that Vesper had a French-Algerian boyfriend who was kidnapped and held for ransom by the organisation behind Le Chiffre and White. Bond learns that she agreed to deliver the ransom money (his winnings) only if they would consent to leave Bond, as well as her boyfriend, alive. He discovers that Vesper has left Mr. White's name and number in her mobile phone for Bond to find. White, arriving at a palatial estate near Lake Como, receives a phone call. As he asks the identity of the caller, he is shot in the leg. Bond approaches, with a UMP in hand, and replies, "The name's Bond. James Bond."
