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...

Day 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...

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...
