What I learned from Quantum of Solace is that the storyline is vaguely similar to Tomorrow Never Dies, but that is no bad thing since in my mind the other three Brosnan movies suffered from being overwritten and don't hold up well to scrutiny. Anyway the basic plot is this:
Mr. White gets captured and interrogated, MI6 learns that he is just the tip of the iceberg and the organization he represents, Quantum, is a highly dangerous and immensely wealthy criminal fraternity with operatives everywhere.
The best lead on the Quantum syndicate is popular industrialist, Dominic Greene, who is currently operating in Bolivia and is suspected of backing the disgraced General Medrano in a coup d'etat, so that Quantum can have exclusive control over Bolivia's water supplies for neferious reasons (most likely financial and resource extortion, but also maybe for a bigger scheme not yet revealed to us).
