All of their hard work is finally done. The SOS Brigade shows off their feature film! A tale of battle waitresses from the future fighting against evil, alien witches, and teenage espers. It will probably make sense… right?

Things are back to normal. Well, as normal as life can be with Haruhi. So of course she wants them to enter… a baseball tournament?! But when the game doesn’t go the way Haruhi wants, danger lurks just around the corner. They’ll have to win, or else.

The skies are overcast with a chance of rain, and Haruhi instructs Kyon to go pick up a heater. With Kyon gone, Haruhi takes pictures of Mikuru in various costumes for the movie's DVD cover, Itsuki helps how he can, and Yuki is left alone to read. After Kyon returns, he finds only Yuki in the club room and decides to wait for the others, but falls asleep. When he awakens, he finds Haruhi alone with him, waiting for him to wake up so they can leave. It has already started raining, so Haruhi borrows an umbrella from school for them to use. When returning home, Kyon finds a more playful side to Haruhi and in the end, she pulls a playful tongue-out face.

On the day of the school's cultural festival, the members of the SOS Brigade are involved in different activities. Mikuru and her class open a fried noodles café, Yuki attempts fortune telling, and Itsuki is in a play. Kyon attempts to enjoy a normal day. Kyon goes to the auditorium, where bands are playing for the audience, and falls asleep. When he awakens, he sees Haruhi walking on stage in a bunny girl costume with a guitar hanging from her shoulders.

Shooting of the SOS Brigade's short film continues. During the battle scene, Haruhi is displeased with Mikuru's acting. She yells at her, demanding that Asahina try to shoot a laser beam from her contact-lens-colored eye, but Kyon manages to cool her down . Afterwards the scene is reshot but, to the surprise of everyone except Haruhi, Mikuru actually shoots laser beams from her eye. Yuki knocks Mikuru down and apparently takes her contact lens. In a conversation Itsuki explains to a shocked Kyon that Haruhi changed reality once again and Nagato proves his words by showing her hand, burnt while protecting Kyon from being hit by the laser. Koizumi promises to take care of Mikuru's problem with Yuki's help. The rest of day is spent on shooting more scenes with Mikuru dressed as a bunny girl. The next day Kyon finds out that Haruhi dragged Tsuruya, Taniguchi and Kunikida to help. After Haruhi gets off to pick up Mikuru, Itsuki explains to Kyon that Yuki succesfully helped Mikuru get over herself. Haruhi returns with Mikuru, who secretely tells Kyon how Yuki helped her: she bit her to inject nanomachines into her body. Haruhi leads everyone to the next shooting location, a lake near Koizumi's house.

As the SOS Brigade shoot more of their film, Haruhi tries to give Mikuru another contact, ergo another superpower. Yuki quickly takes action and injects her with more nanomachines before any damage could be done. Despite the weird phenomena Haruhi's film is causing, Itsuki suggests it is better than more closed spaces being opened up. However, when Kyon discovers Haruhi arranged for Mikuru to be drugged for a kiss scene with Itsuki, he gets furious at her shabby treatment of Mikuru and almost hits her, forcing Itsuki to hold him back. This causes Haruhi to become depressed, having always thought Kyon would support her. Kyon, reluctantly learning something from Taniguchi, later apologizes to Haruhi and filming resumes. However, he seems to have inadvertently encouraged Haruhi even more, making cherry blossoms grow out of season.

Deciding Yuki needs a familiar for her role, Haruhi picks up a stray cat and names it Shamisen. However, when Haruhi leaves that day, Shamisen starts talking as a result of Haruhi's powers. Itsuki suggests that they need to remind Haruhi her movie is a work of fiction, before reality takes any more damage. The next day at school, Mikuru gives him a coupon for her class's yakisoba café, and gives her views on Haruhi that she couldn't say in front of Itsuki. Kyon later talks with Yuki, who throws up the idea that one of them, including herself, may be lying. As shooting resumes, Haruhi's powers to continue to make Mikuru a deadly weapon. Itsuki calls Kyon out later that night, asking him to find a way to hold back Haruhi's powers. Kyon convinces Haruhi to add a disclaimer at the end, saying the film is a work of fiction, and the rest of the shooting goes without a hitch. Kyon falls asleep whilst editing the movie, only to find it has edited itself overnight. At the very last of this episode, there is a flashback to May that Kyon tries telling Haruhi that Yuki, Mikuru and Itsuki are actually aliens, time travelers and espers, but she doesn't believe him.
