It was of a family, the father and mother were in the FBI or CIA. They tryed to keep the identity of a normal family, but they were really secret agents who lived double lives. Somehow I remember the kids, 1 boy and 1 girl being involved with helping keep it all a secret. It wasn't around long, but it was on in either 1998, or 1999.

I would definately remember the title if someone else knows and posted.

Cover Me: Based on the True Life of an FBI Family?

EDIT: Actually, this was a drama, not a sitcom, if I recall correctly.

That's exactly it, thank you.
