On the way to school, Sakura meets Maki Matsumoto who is opening a stuffed doll shop called Twin Bells. Sakura and her friends visit the shop after school to find most of the merchandise unpacked, so they offer to help. Chiharu Mihara, who has a fondness for stuffed animals, buys a stuffed panda, but it disappears shortly after taking it home. Sakura discovers the panda back in Twin Bells and Maki explain the reason for opening the shop and her business has been plagued by mysterious happenings that almost forced her to close down. While Tomoyo distracts Maki in the back, Sakura and Kero search the shop to find The Jump, which escapes with all the stuffed dolls in the shop. At Penguin Park, The Jump grows into a giant by absorbing the stuffed dolls, but it knocks itself out after it trips and falls allowing Sakura to capture it.

Sakura, usually cheerful, is forlorn by Syaoran's confidence and obviously superior skill. Rika and Tomoyo take Sakura to a shop to try to cheer her up. The three each buy brooches and return to Sakura's house for tea and pudding. When Rika puts on her brooch, The Sword takes control of her and attacks Sakura with a sword. Syaoran saves Sakura who refuses to attack Rika and stops him from attacking her as well. Using Illision to distract Rika, Sakura is given the chance to capture Sword. The next day, Syaoran is dismayed when he sees Sakura offer a gift of chocolate to Yukito, and quickly gives sweets of his own. Tomoyo has to explain to Sakura that Syaoran is "interested" in Yukito just like Sakura is.

Sakura and Kero encounter some problems with time as Sakura, Kero and Syaroan find that they are the only ones who realize that Time is starting the same day over and over and over again. It's time for Sakura to take action and capture this time-meddling Clow Card!

Sakura's family and Yukito takes a vacation to the country side. Sakura meets the old owner of a country mansion near their rented cottage. He invites her over for tea, tennis, and they become good friends. He shows her the room of his granddaughter, now deceased, and gives Sakura clothes that once belonged to her. The next day, Fujitaka gives Sakura cookies to give to the old man. When she brings them out to eat, the old man asks her about her father. On the last day of her vacation, Sakura asks the old man to stand in the balcony of his granddaughter's room. From a distance, Sakura uses the Rain card to give the old man a rainbow as a goodbye gift. Sonomi comes out of hiding to speak with the old man to reveal the old man is the grandfather of both Sonomi and Nadeshiko, and Sakura's great grandfather.

The summer holidays are coming to an end and Sakura still has a lot of summer vacation homework to do. Making a deal with her brother and Kero to help her, Sakura is left with only a book report and meets with Tomoyo at the library. There, they meet Syaoran who refuses to share a library cubicle with them because his fortune predicted bad luck with women. The book Sakura needs for her book report is missing so Sakura and Tomoyo search the library, but notice the book disappearing and reappearing in different places. The book eventually appears outside the library where they meet Syaoran who is also after the book. Kero reveals it’s the work of the Move card and for the first time, thanks to Move's unpredictable actions, Sakura is forced to rely solely upon her magical senses to catch a card. Sakura is rewarded with the book and a new card, but accidentally plunges into the river, taking Syaoran with her. Syaoran invites the girls over to his place so Sakura can change into dry clothes, but to everybody’s surprise, a Chinese girl enters the apartment and leaps on Syaoran with a hug.

During a school race, Meiling is determined to win with Syaoran, in their usual "One-Two Finish" they were known for in their previous school. During the race, both Syaoran and Sakura take off at top speed after seeing that Yukito is watching. As the run, the Loop card causes traps Sakura and Syaoran, causing them to run in circles. After they realize what has happened, Sakura is able to use the Sword card to cut the loop. Syaoran carries Meiling, who hurt her ankle, the rest of the way to the finish line, joined by Sakura.

On her way home Sakura bumps into a woman in the street. After arriving at school the next day, Sakura discovers that her math teacher will be on extended vacation and the replacement is the woman she bumped into the day before, Ms Mizuki. During the lunch break Syaoran reveils to Sakura and Tomoyo that the substitute has a strong magical presence and that they should be careful around her. When school finishes Sakura and Tomoyo go to a shrine to pick up a romance charm. Upon arriving Sakura feels a presence. While at the Shrine they also see Meilin and Syaoran. After a brief conversation they are all transported into a labyrinth, it is soon discovered that this is the work of the Maze card. A number of escape attempts using the Fly and Sword cards are foiled. The Maze then starts to change shape and Meilin is separated from the others. While searching for Meilin, they find her with Ms Mizuki and they soon escape the labyrinth with Ms Mizuki's help. The Clow Card is then captured, however it goes to Ms Mizuki who promptly goes on to give it to Sakura.
