Plot
Maki is the daughter of the scientist Kimihiko Nikaido. When Dr. Nikaido was in his lab waiting for his assistant Dr. Kimiko so he can inform her something, a bio terrorist group appeared in his lab. Dr. Nikaido then arrived and admitted to him that she's the leader of the group. She tells him to hand over the antidote of the invented virus because she couldn't continue her plan to wipe out much of humanity without it. Dr. Nikaido refuses, and she threatened him, telling him that they'll see which is more important to him, Maki or the antidote. Mean while, Maki arrived at the lab, and she went upstairs to find her father cornered by Kimiko and the bio terrorist group. She hid behind a wall and watched. Dr. Nikaido then takes out the antidote, and put it somewhere where it'll be destroyed. Then, he takes out the sample of the virus he got, and injected himself with it. While the virus took affect, Kimiko pressed a button which let electric sparks fly around the lab. Maki, hidden behind the wall, watched as her father die gruesomely.

Maki runs out to the car that she arrived with, and she told the car driver to drive to every adress recorded on her phone. She cries and cries all the way on the ride.

In L's headquarters, he recieves a video chat with Kimiko telling him that she needs the antidote to the virus, and Dr. Nikaido was murdered by someone. Now she needs his help tracking it down. In reply, L tells her to meet him in his headquarters. After the chat, someone from the entrance of L's headquarters tells him that they need Watari. As it turns out, it is Maki's driver. Then, L tells Maki that she can come into the headquarters.

When Maki is there, Kimiko and the terrorists enter the headquarters and set off an alarm. Maki runs out of L's office and faces her alone. During their encounter, Maki injects herself with the virus, and was about to get shot. L rescues her from the terrorists and brings her and Near through a secret door in the hallway. While going through a couple of staircases, they meet an FBI agent who then helps them. L brings all of them to his pink truck that they use to escap.

The FBI agent drives the pink truck, L, Maki, and Near all throughout the town, drawing a lot of silly attention to themselves. L makes him stop at a market and he and the kids go inside. During their stay at the marketplace, L buys various things and makes a small transmitter that proves to be useful later.

Meanwhile, Kimiko is planning to track down Maki because of suspicion that she may have the antidote injected in her.

When a talk between L and the FBI agent is finished, the agent is once again stuck being the decoy, while L, Maki and Near travel on the train to meet a scientist named Matsudo. While on the train, a television broadcast by Kimiko alerts the citizens that Maki is infected with a deadly virus. They get off at a stop, and cease using public transportation. In order to stay hidden, they ride bikes around the small town and Maki changes into a red dress so that people will not recognize her in her school uniform.

When they arrived at Matsudo's lab, L tells him that they need him to create the antidote. After some persuasion from L, Matsudo accepts the job.

While making the antidote, Matsudo encounters many problems. After several failed antidotes, they arrive at a breakthrough. A drawing made by Near on a chalk board lead Near to a conlusion: 13 and 11. Through that, L is able to figure out MK, which means Midkine. Midkine may be a significant ingrediant to the final antidote.

Maki has a picnic on the lab roof with L and Near. L and Near begin eating quickly, and Maki scolds them for not bowing and saying thank you before eating. After eating their food, Maki encourages L to try and stand up straight. After L successfully stands without hunching over, Maki and Near clap for him. With their picnic over, Maki says that she needs to use the bathroom. When L and Near are gone, she runs and leaves the lab by her self. At night Maki arrives at a doc, where she had arranged for Kimiko to meet her there alone. Maki is kidnapped by the terrorists who end up taking Maki away for their experiments across the country. L runs to rescue her but is too late.

L returns to the lab, finding out that Matsudo had already finished making the correct antidote, but it hasn't been tested yet. Matsudo then makes many more, and L takes all of them. He and the FBI agent then go to save Maki, driving to the airport in the pink truck.

On the airplane, Kimiko has Maki in an operation room, but the captain of the plane tells the passengers that there's an unauthorized viehcle on the runway. Kimiko realizes that it's L's truck, and she takes Maki out of the operation area. At this time, one of the terrorists has already been infected by the deadly virus because of Maki's injection. The terrorists take out guns hidden in Maki's operation table. Kimiko commands one of the terrorists to take the plane off the ground. L's truck makes it just in time, and L jumps from the enterpath into the moving plane.

Meanwhile, the passengers on the plane begin to be infected. The terrorist pilot of the plane dies, and the plane goes out of control. Kimiko starts to get infected as well. She thinks the plane will take flight, and the virus will spread. But L had also brought the transmitter he made earlier on with him, he says that its magnetic pull is strong enough to stop the plane.

As Kimiko dies, L injects the antidote into her, and tells a flight attendent to give everyone on the plane a shot of the antidote. Maki gets a shot before it was too late, and so did everybody else. L then runs to the plane's control booth, and stops the plane before it crashes into the airport.

Maki sees a knife laying beside Kimiko, and attempting to kill her, picks it up. L arrives just in time and convinces Maki to put the knife down. Maki tells Kimiko that it's okay, and she begins to cry. The ambulence arrives and takes the sick passengers away to the hospital.

At the end, Maki wakes up and finds her teddy bear with L's voice recorded in it. L tells her "Welcome home Maki, please have a good day tomorrow, too."
