Burn Notice, Season 3

Michael:
[V.O.] When you realize that an operation is compromised, that your enemies are on the move, you're on the clock. You have to move as fast as you can to contain the damage and harden your defenses before it's too late. Sometimes you make it in time, and sometimes you don't. When you work in intelligence, the worst feeling in the world is knowing nothing. Being caught in something you don't begin to understand, because it's not the enemy you see that gets you. It's the one you don't.
