Or, heres a more detailed explanation. Spoiler too.

(SPOILER)Well, you snuck in Alexandria Castle, did a play, then kidnapped Princess Garnet. Then you got shot down, went to the evil forest, then the ice place, then lindblum, and then the grotto place, and got Quina (right?), and then went back to lindblum, got drugged, now your in Bermica. You'll see a few scenes, and then you'll fight Beatrix, then another scene with Kuja, and blah.
That's enough for now. I shan't tell you the rest xD
