24 is an Emmy and Golden Globe award-winning American action drama television series. Broadcast by Fox Network in the USA and syndicated worldwide, the show first aired on November 6, 2001, with an initial thirteen episodes. The first six seasons were all centered around the Los Angeles branch of the U.S. government Counter Terrorist Unit (CTU).

24 is presented in real time, with each season depicting a 24-hour period in the life of Jack Bauer, who works with the U.S. government as it fights domestic threats. Bauer is often in the field for the Los Angeles Counter Terrorist Unit as they try to safeguard the nation from terrorist threats. The show also follows the actions of other CTU agents, government officials and terrorists associated with the plot. The first six seasons of the show were all based in Los Angeles and nearby locations  — both real and fictional  — in California, although occasionally other locations have been featured as well  — most notably, Washington, D.C., where a notable portion of the episodes took place during the fourth and sixth seasons. Promotional materials for the seventh season have already established that, departing from tradition, it will be set primarily in Washington, D.C.
