Yuuichi Katagiri has battled financial hardships his whole life but has learned to stay content and positive thanks to his close circle of friends. To keep a promise he made to them, Yuuichi saves up enough money to join them on the school trip. But when the gathered money mysteriously goes missing, suspicion falls on two of Yuuichi's friends: Shiho Sawaragi and Makoto Shibe, who were in charge of collecting the payments. Although innocent, Shiho and Makoto take responsibility for the failure to protect the money when no one else comes forward. A few days later, Yuuichi and his friends receive mysterious letters which trick each of them into meeting up. Upon arrival, they are ambushed and knocked unconscious. They wake up in a mysterious room in the presence of "Manabu-kun," a character from a controversial children's show that stopped airing due to its malicious content. He informs the group that one of them indirectly gathered them together in order to settle a large debt. They are to play a "friendship game": a series of games that will test the strength of their bond and trust in each other. As the group's faith wavers due to the growing number of secrets and betrayals, Yuuichi must figure out who of his "friends" he can actually trust and ultimately discover the identity of the traitor.

Smart, refined, and strikingly gorgeous, half-Russian half-Japanese Alisa Mikhailovna Kujou is considered the idol of her school. With her long silver hair, mesmerizing blue eyes, and exceptionally fair skin, she has captured the hearts of countless male students while being highly admired by all others. Even so, due to her seemingly unapproachable persona, everyone remains wary around the near-flawless girl. One of the few exceptions is Alisa's benchmate Masachika Kuze, a relatively average boy who spends his days watching anime and playing gacha games. Despite his nonchalant demeanor, Masachika is the sole student to receive Alisa's attention. Unable to be fully honest, Alisa is frequently harsh on Masachika and only expresses her affection in Russian. Unbeknownst to her, however, Masachika actually understands the language yet simply pretends otherwise for his own amusement. As the odd pair continues to exchange witty and playful remarks, their relationship gradually grows more romantic and delightful—and Alisa might finally learn to freely convey her true feelings.

Energy-conservative high school student Houtarou Oreki ends up with more than he bargained for when he signs up for the Classics Club at his sister's behest—especially when he realizes how deep-rooted the club's history really is. Begrudgingly, Oreki is dragged into an investigation concerning the 45-year-old mystery that surrounds the club room. Accompanied by his fellow club members, the knowledgeable Satoshi Fukube, the stern but benign Mayaka Ibara, and the ever-curious Eru Chitanda, Oreki must combat deadlines and lack of information with resourcefulness and hidden talent, in order to not only find the truth buried beneath the dust of works created years before them, but of other small side cases as well. Based on the award-winning Koten-bu light novel series, and directed by Yasuhiro Takemoto of Suzumiya Haruhi no Shoushitsu, Hyouka shows that normal life can be full of small mysteries, be it family history, a student film, or even the withered flowers that make up a ghost story.
