Found the answer from a gamespot Interview:
GS: What can you tell us about the story?
DR: At the beginning of SC4, Sam Fisher's life is thrown in disarray when his daughter Sarah dies in a car accident. After months of psychological depression, he accepts an unusual assignment from Irving Lambert and goes undercover inside an American terrorist organization operating on American soil. To see what happens next, you'll have to play the game... Let me just say Sam will be faced with tougher decisions than he's ever faced before.
