Haruhi Suzumiya is an eccentricity who dislikes the ordinary. If she could just meet an alien, time-traveler, or esper, her life would be made! Unfortunately, things just aren’t interesting. Until she decides to shake things up with her own club.

The SOS Brigade is now open! First, they need a computer for their club, and Haruhi is determined to get one. But is extortion the answer? Next, they need more members. And that requires… bunny outfits?! Finally, Yuki opens up to Kyon with a bizarre reveal!

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.

Kyon is still processing what Yuki told him. Meanwhile, Haruhi’s wish comes true! A mysterious transfer student appears and joins the club. With five members, they can finally start on… whatever they do! But what’s up with the crazy reveals from everyone?

The SOS Brigade is going on a summer retreat. And what better way to enjoy a summer retreat than on a deserted island? But if the mysterious island mansion doesn’t live up to Haruhi’s expectation, will she cause another incident? Or something worse?

A new visitor appears with Mikuru to enlist the SOS Brigade to find her missing boyfriend, who happens to be the computer club president that Haruhi extorted. As they go on the hunt for him, a closed space begins to form. Can they save him in time?

Haruhi gets her wish for a murder mystery when the master of the house is found dead! But an actual murder may be more than she can handle. As they work to solve the case, things become more and more dangerous. Can they figure it out?

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.

Haruhi is visibly bored and is not her usual energetic self. Ryoko Asakura, the class president, is concerned and asks Kyon to help her. Kyon later finds a mysterious letter in his locker, which directs to come to a classroom, where Ryoko confronts him. Revealed to also be an alien, Ryoko attempts to kill Kyon in order to provoke a reaction from Haruhi, but is stopped by Yuki. Later, Kyon meets Mikuru's older self that had traveled from the future, who reveals that Snow White is the clue essential to his future. Ryoko was reported to never have transferred into the high school, much to Haruhi's suspicion.
