well originally it was about the main girl, jennifer garner, going to work for what she thought was the CIA but it was actually these bad guys, SD-6. so she went double agent on them and began working through the real CIA. last year they destroyed SD-6. but its leader is this evil dude whose passion was Rambaldi artifacts. at the end of the season something crazy happened. now its two years later and jennifer garner is trying to find out what happened to her. that's just a overview though. there is a shitload of stuff that has been and is involved in the plots.
