As November 22 approaches it will become harder and harder to keep the major plot of Catching Fire a secret. The second official trailer was unveiled at this weekend's Comic Con, and finally the major plot was revealed. If you still want to avoid knowing what exactly will happen, do not watch the new trailer.
If the trailers are anything to go by, Catching Fire will not disappoint. I especially love the quick peek at the scene where Katniss changes into the Mockingjay.
Here is the video of the Catching Fire Comic-Con panel. There's not much new information, but beware, Lenny Cravitz (Cinna) drops a major spoiler around minute 08:30 - 09:00.
