Jack's opening monologue is introduced in this episode - "Right now, terrorists are plotting to assassinate a presidential candidate, my teenage daughter is missing, and people that I work with may be involved in both. I'm Federal Agent Jack Bauer. Today is going to be the longest day of my life." It will change over the course of the season as Jack's life changes.
This episode won an Emmy for editing (Chris Willingham) and received an additional nomination for dramatic underscore (Sean Callery).
