The first season of the American drama television series 24, also known as Day 1, was first broadcast from November 6, 2001, to May 21, 2002, on Fox. The season's storyline starts at midnight and ends at the following midnight on the day of the California presidential primary. Season overview The first season takes place on the day of the California Presidential Primary. The season's main plot revolves around an assassination attempt on David Palmer, a U.S. Senator from Maryland who is a candidate for the Democratic Party presidential nomination, on the day of the primary in California. The central character is Jack Bauer, a former United States Army Delta Force operator who is the Director of the fictional Counter Terrorist Unit (CTU) in Los Angeles. Bauer becomes professionally as well as personally involved when his wife Teri and daughter Kim are kidnapped by the people behind the assassination plot.
