Day 5: 9:00 p.m.-10:00 p.m. 

Jack is forced to interrogate Audrey when he learns that she might be connected to Bierko and the terrorists. Although he is convinced of her innocence Karen Hayes is unconvinced and decides to push Audrey harder, forcing Jack and Chloe to search for evidence that Stenger is lying.

Eventually Stenger admits that implicating Audrey was a ploy to throw CTU off, and informs them of Bierko's next target. Wayne and Pierce manage to link up and flee from armed men who have orders from Henderson to kill them.

Bierko and his men execute the next phase of attacks by targeting a gas company and releasing the Sentox gas throughout Los Angeles. Jack and Curtis lead a TAC team to stop Bierko, but are too late to prevent the Sentox being released. Jack then sets C4 charges on the main gas pipe to destroy the gas before it can reach the main gas tank. Jack captures Bierko just as he is trying to escape.

In summary,here the events that happened during that hour:

1.Vladimir Bierko prepares to release the remaining canisters of Sentox nerve gas into the main distribution tank at Wilshire Gas Company.

2.Christopher Henderson asks if Wayne is dead.

3.Aaron Pierce rescues Wayne as he is under attack.

4.At Counter Terrorist Unit Jack Bauer is forced to interrogate Audrey after she was named as a contact by Collette Stenger. After questioning

5.Audrey and believing her to be innocent, Jack and Chloe found a link between Henderson and Stenger and realized that Audrey was being set up. Jack forces Stenger to reveal Bierko's target.

6.Jack Bauer tracks Bierko to the gas company and fights with him as the main tanks explode.

Jack interrogates Audrey all of a sudden after Colleen Stenger,the sexiest mercenary,implicates her.Will Jack torture her to extract information?It looks like that he is willing to do so for the sake of millions of lives that are in danger.But later on,Colleen admits it was all a lie.

Having Audrey involved with the terrorists would have become a big pirouette on her character development considering that she and her father were initially kidnapped by the the terrorists.Anyway,Richard Heller did have something to do with them so it would probably not be unbelievable.But anyway,torturing a woman would probably be too violent in TV that is why the writers addressed this issue right away.

Also,we see that Jack and Curtis try to capture Bierko.But unfortunately,Bierko escaped and eluded them.Yes,he escaped.Why?I guess it is not time to end the show yet or it won't be entitled 24.LOL
