http://www.tvtome.com/24/Welcome to the 24 guide at TV Tome. 1 : This groundbreaking thriller is a roller-coaster ride that unfolds in real time. From midnight to midnight -- covering a 24-hour day over the course of a season -- each episode will have its own resolution, but the clock will never stop ticking. The first 24 episodes take place on Presidential primary day in Los Angeles, where Jack Bauer and his elite team of CIA agents uncover a plot to assassinate Presidential nominee David Palmer. With only 24 hours to identify the killer and save Palmer's life, Jack must also deal with his strained marriage and the sudden disappearance of his troubled teenage daughter. The clock is ticking...
2 : Season two picks up approximately 18 months after the conclusion of the first season, and finds Jack Bauer, who headed the government's Counter Terrorist Unit, dealing with a personal tragedy. Just as his life is beginning to return to normal, now-President David Palmer reaches out to Jack, who is called upon to stop another terrorist plot with global implications. A nuclear bomb is set to go off sometime that day in Los Angeles, and Jack may be the only one who can stop it. But time is running out...
3 : Season three starts three years after the events of the second season. A South American drug lord sits in jail, put there by Jack. His brother arranges to blackmail the US Government with the threat he will release a bio-weapon that will kill millions if they don't release him. Palmer seeks re-election to a second term, with a dodgy chief of staff, and a girlfriend who may not be telling him everything he needs to know. Will Jack survive this day? Or will it be his last...
4 : Eighteen months after the conclusion of Season 3, CTU has a new leader, Erin Driscoll, a steely government agent who made firing Jack one of her first priorities.
After the explosion of a commuter train, Jack, who is now working for Secretary of Defense James Heller and also is romantically involved with Heller's married daughter, Audrey Raines, suddenly finds himself heading back to CTU for a meeting with Driscoll. Jack believes that the train explosion is a prelude for bigger things to come and as this day unfolds, he finds that his instincts are right.

http://www.lethaldeath.com/Crimson/Archives/ResidentDVDvil/Archives/RD_24_Season3.phpThe 3rd season takes the storyline 3 years after the events of the 2nd, where we learn that Palmer is still in office and Jack has been involved in an undercover operation that has taken an extremely hard toll on him. Tony Almeida (Carlos Bernard) has now taken the reigns as the head of the CTU office, and is now married to Michelle Dressler (Keiko Aylesworth). I was glad to see so many of the characters back. Until I saw Kim. She was almost the nail in the coffin for my hopes of a good season, and though I could have done without her character anywhere in the series this season, at least the writers made her an employee of CTU in order to explain why her day would be as bad as her Dads.
