You should just watch Casino Royale. It's fucking great.
Bond is betrayed by the love of his life, Vesper. She was plotting to steal his winnings from the poker game in order to save her long time boyfriend from blackmailers and release him from captivity. Bond found out and ran after her. He looked out on her as she started the transaction with her blackmailers but soon gets made. As all hell breaks loose, Vesper becomes trapped in a watery tome. There was a possibility of her being rescued, but she chose to die in order to spare Bond the agony of deceit. Bond still manages to bring her to the surface, but soon realizes he is too late.
And now, in this movie, Bond is a cold, heartless killer looking for one thing; Revenge.
Oh and by the way, the main "hot" chick, Olga Kurylenko, is stunning.
