Day 2: 4:00 PM-5:00 PM
As the pilots struggle to control their damaged plane, Jack tries to get Nina to divulge the location of the nuclear device planted in Los Angeles. But convinced that not telling him is the only thing keeping her alive, she refuses---even as they're told to prepare for a crash. Meanwhile, CTU finds the source of the plane's problems; President Palmer learns the identity of at least one person working against him; Kate is questioned about her father's files; and Mason reveals his condition to Tony as they try a different tack in interrogating Warner and Reza. Koplin: Al Sapienza. Ali: Francesco Quinn. Sherry: Penny Johnson Jerald. Warner: John Terry. Reza: Phillip Rhys.
