The following takes place between 3am and 4am. Events occur in real time.

A black van drives towards the local office of the CDC. All the men inside wear masks. At this time of the morning it's unlikely anyone could see them, but there's no reason to take foolish chances. They reach their destination and two people carry the dead body. The third man plants a small explosive device, and sets the timer for thirty seconds. All three quickly run to the van and drive off. The bomb goes off, and quickly gets the attention of the few security guards and janitorial staff in the building at 3am. The find the body, and a DVD, someone is clearly sending them a message.

Kimberly Bauer wakes up in her cell. She sees the clock, 3:03am. At midnight she's scheduled to be executed by lethal injection. 21 hours from now she might still be alive, but 22 hours from now she'll be dead. Kim thinks back to that day, five years ago. Gary Matheson was a monster who abused his wife, his nine year old daughter. He murdered his wife, murdered the cop who was protecting Kim. But Kim didn't have to kill him, she could have just gotten out, called the police so they could arrest him. If she had done that, Gary would probably be the one on death row right now. But her father had encouraged her to shoot him, to make sure she was safe. And now, here she was, less than 21 hours away from being executed. A part of Kim blame her father for this, but he was doing all he could to get her out of here. Kim didn't believe she had a chance. Jack would move on with his wife Kate, and Kim would be dead.

President Charles Logan was asleep in Los Angelas. In a few hours he was meeting with Kim Chul Eun, the dictator of North Korea. Logan hoped to be able to convince Kim to end his country's nuclear and chemical weapons program in exchange for an aid package of food and medicine. Logan had a plan to learn if he was serious about disarmament, but it was risky. He hoped to be able to get some rest before the big conference, but no such luck. Aron Pierce, a Secret Service agent, woke Logan up.

.

Logan: What is it Aron?

Aron: A dead body was recently left on the offices of the CDC, it was infected.

Logan: Infected with what?

Aron: A recording says that it's the cordella virus. We need to move you to a secure location.

.

At CTU Los Angelas Tony Almeida and his team are alerted to the problem. There aren't many people here at 3am, a number of their agents are about to be woken up and called into work. Tony briefs the people already here.

.

Tony: Ten minutes ago someone dropped off a dead body that was suppossedly infected with the cordella virus. They are running tests now to verify this, for now we should work under the assumption that this group has possession of the virus. According to the DVD they left, this group is calling itself the Worker's Army. Suppossedly this group is a fanatical group from North Korea trying to prevent chairman Kim's reforms, including trying to stop the peace talks between him and president Logan. We need to find any affiliates this group might have in the U.S., and whether there is any link between them and the North Korean government.

.

As his team gets to work on this Tony fears this could interrupt what he'd planned for later. He had hoped to do this meeting covertly, at 3am very few people would be here. Now, new agents coming in, someone might see something. This was problematic.
