After a strange dream, Syaoran wakes up in a futuristic world called Piffle and joins the others. After a chat with Yuuko, the group sets out to take part in the Dragonfly Race; the grand prize is one of Sakura's feathers!

Nearly crashing into her, Sakura and the others meet Tomoyo Daidouji, the president of the Piffle Princess Company and hostess of the Dragonfly Race. Tomoyo decides on Sakura as her heroine for the race; unfortunately, Sakura is not the best driver and she crashes more than once.

While Syaoran, Fay and Kurogane ponder which of the contestants interferred with the qualifying race, Sakura is chosen for the pole position in the final race. Afterwards, at a party thrown by Tomoyo, Syaoran rekindles his friendship with the Ryuuoh in Piffle.Later, Syaoran is attacked, but the fight is called off only for the group to discover Tomoyo is intently investigating the incident during the qualifying race and she asks Sakura and the others for their assistance. Then, Tomoyo decides to make a costume for Sakura (and Mokona) for the Dragonfly Race; Syaoran seeks advice from Ryuuoh and the race begins!

Sakura continues racing in her dragonfly while avoiding obstacles. Meanwhile, using the sensor, Syaoran and Ryuuoh find out where the interference for the race is coming from. They head over to the Piffle Corporation Building and find that Tomoyo’s secretary is the one behind the sabatoge. When they arrive they find that he is about to shoot down Sakura’s dragonfly. Can Syaoran and Ryuuoh stop him?
