This episode focuses mostly on the Warners. One assists Jack in trying to come up with the main terrorist. The other is a sociopath who is in deep. She is the one that needs to get a trigger for the bomb being kept in a locker. The father continues to be held at CTU. Kim is in running from the law and gets herself caught in a trap, approached by a mountain lion. The one thing that needs to be dealt with is why the lily white Marie is working with the terrorists.
