The episode starts out in Tokyo, Japan somewhere in the future. Cars have been modified to run on electricity with AI units driving people to and from their destinations similar to taxis. Within the first few minutes, we see a car go out of control with a family inside of it. Lorna Endou and Lisa Sakakino, two eX-Drivers in Japan, take on the challenge and help disable the malfunctioning car. The girls go out to a bar afterwardsto relax after their victory, Lisa complaining about how the job is boring while Lorna tries to point out how much of a thrill it is to enjoy driving and helping people. The two are soon contacted by their boss and scolded since they have classes in the morning and are still out so late. they make their way back to the cars but not before being harassedby a few punks. The punks immediately recognize the girls as the eX-Drivers and try to leave but Lisa activates an illegal booster mod to make the car zoom off. After letting a few children examine their cars, Lorna notices the modified car from earlier swirve around a corner fast, getting a call soon after about the car they just saw.
After chasing it around for a few minutes, HQ informs them to get in close to take the car out. Lisa attempts to do this but the AI car rams her, her vehicle spinning out of control and crashing into the curb. The Chief of Operations realizes the car was modified by a group called the Underground as Lisa proceeds to cut off the car on foot while Lorna pursues it in her car. After a few more feeble attempts to disable the car, Lisa joins up with Lorna in her car to chase the AI vehicle out of the city so it won't endanger anyone else. However, the girls still are unable to disable the car and as things look hopeless, another eX-Driver appears to help take down the modded car. After successfully doing so, Lisa runs to see who it is as she said earlier that the man of her dreams would be someone who is smart, a better driver than her, and cute. To her dismay, 12 year old Soichi Sugano emerges from the car, surprising Lisa who goes off to sulk as Lorna thanks him for the help.
The next morning has Lisa and Lorna running to school, being late as the two were up working and did not get much sleep during the night. As the classes start in the morning, their teacher introduces a new student: Soichi Sugano who is apparently a child prodigy who skipped grades to be in the same class as the other two eX-Drivers. Lisa sulks and groans about the situation and how Soichi is also an eX-Driver as the group gets a call about a new malfunctioning vehicle in the city, prompting the group to head out for action.
