There's a 24 board, if you wanna check it out.
The bad guys enter gas plant to release their chemical, but need the pressure reduced by 50% to do it. CTU spots the drop in pressure and Jack gets there (surprise) JUST IN TIME to save the population, but too late to stop the bad guy (who slips away during a gunfight) from releasing the chemical. In order to save the day Jack has to blow up the gas plant and is almost caught in the flames, but continues to run ahead of explosion after explosion to safety. He goes back in after the bad guy, drags him out, and they are both in a cop car as another explosion throws debris and flames around the car - End of Show.
Chloe finds evidence that Audrey is withholding knowledge & sleeping with the enemy (literally). Jack questions her - slams her against the wall with his hand on her throat, like he does - but believes her that she didn't know he was a bad guy and she dumped him after one night because, she tells Jack, "he wasn't you." Not everyone at CTU is buying this, so they send someone else in to get info out of her. Jack gets the bad woman to tell him she falsely accused Audrey, and stops Audrey's interrogation. The audience is left wondering if she's another Nina Myers.
Wayne Palmer goes to the White House to give info to the dopey new President, but is attacked by a bunch of guys who we assume were sent by the Vice President. That sweetie-pie secret service guy helps him and drives him out.
A new girl shows up at CTU to replace Edgar. Big tension between her and another guy at CTU with whom she'd worked in another office. She tells Chloe he sexually harassed her, he tells Chloe she's a big, fat liar. Then she gets all psycho-worked up because another guy touches her shoulder for a second as he tells her, "good job." Only Chloe realizes what is going on (that she's psycho).
I think I got it right.
