24 star Kiefer Sutherland believes that the series could be revived in many different ways, either with Jack Bauer at the helm, or focusing on a different situation beyond Jack's terrorism task force. 24 focuses on Counter Terrorist Unit (CTU) Agent Jack Bauer, with every 24-episode season centered around a day-long timeframe in Jack's life, typically trying to stop a terrorist plot within the span of 24 hours. Each episode of the series happens in the show's real-time, making the season-long storylines unique to other crime dramas.
