My name is Sydney Bristow. Seven years ago I was recruited by a secret branch of the CIA called SD-6. I was sworn to secrecy, but I couldn’t keep it from my fiance. And when the head of SD-6 found out, he had him killed. That’s when I found out the truth. SD-6 is not part of the CIA. I was working for the very people I thought I was working against. So I went to the only place that could help me bring them down. Now, I’m a double agent for the CIA, where my handler is a man named Michael Vaughn. Only one other person knows the truth about what I do, another double agent inside SD-6, someone I hardly know - my father
Vaughn: This watch belonged to my father. It’s broken now, but it used to keep perfect time. And when he gave it to me, he said, “You could set your heart by this watch”. It stopped October 1st: the day we met.
