The film opens on a red screen, while we can hear the sound of a baseball bat hitting something, the beginning shows us the different companies' names (also 07th Expansion) and pictures of bloody corpses, blood on a table and a window where we can see the shadow of a bat hitting something.
The scene switch in a bus where many people are sitting, one is a young man and he listens to music, he is Maebara Keiichi and is sitting next to his mother, Maebara Aiko. The camera, now outside, show the bus which the sign shows "Okinomiya - Hinamizawa". The bus drives on a road near of a pile of logs and pass a lot of signs which shows "Hinamizawa dam construction area".
The logo of Higurashi no Na ku Koro ni appears and pictures (such as one of the Irie Clinic) comes after with an opening for the film.
The bus finally arrives to the Hinamizawa Bus Stop and the camera shows the payphone. Aiko and Keiichi, with a large Adidas black bag, go out of the bus, followed by three other persons. Aiko enters the payphone and listens to the phone while Keiichi stays outside. He looks at the village and a date with a place name are shown "1983, 05th, 12, Hinamizawa Village, Shishibone".
A white screen flashes and, while kids are singing, we see Keiichi arriving with his mother at the Hinamizawa Branch School. He enters it and we now see him following a nice dressed woman in the stairs. While he is climbing the stairs, Keiichi looks at draws hanged on the wall, arriving at the second story, he sees a dragonfly on the side and the woman looks also to it. They then enter a corridor where Keiichi sees a draw of demons killing children, they enters the classroom as the women opens the door and a board brush falls on her head and chalk dust is poured on her. All the students happily stand up and applaud themselves for this nice joke. The woman asks her to calm down and asks the children who did this trap. She asks "Satoko-chan ?" and the girl directly stands up holding her right hand. The woman who seems to be the teacher asks her 'You did it, right ?" but the girl answer.png.pngs "It wasn't me.", she then asks another girl, "Rika-chan", to tell the truth, but the girls answer.png.pngs that she doesn't know who is the culprit. She calls another girl, "Rena-chan" and asks to say the morning greetings because she is "on day duty today". The girl asks the stands to stand up and to bow, then all of them say "Good morning (お早うございます. ・ohayō gozaimasu)", and finally she asks to sit down. The teacher tells them after having write the kanji name "前原 圭一" on the board for "Maebara Keiichi" that she wants "to introduce a new transfer student to this school". Keiichi take his bag in his hand and introduces himself "I'm Maebara Keiichi, I came from Tōkyō. Nice to meet you.". All the students tell the same while Satoko turns to Rena before they all clap their hands, then another girl turns to Rena too and smiles.
The teacher tells him that he can sit in "that open seat there.". while he walks to the seat, he looks at the four girls we've seen before whom look at him too. After he seats, the one who wasn't presented approaches him and introduces herself as "Sonozaki Mion, the class president", she stretches her hand but Keiichi totally blanks her as she stares at him.
Pictures of the sky are shown and a black screen appears where is writed "one month later". In a house, a painting is putted on a easel. Aiko goes out of her house and give a foodplate to her husband Maebara Ichirō who is painting while Keiichi arrives on his bicycle and says that he goes out. His father asks Aiko where is he going and she tells him that "his friends from school are showing him around the village". His father says that it means Keiichi is completely blended in now and her mother reminds him when Keiichi was always saying "I want to go home already" persistently, even thought they have been worried about him, then, while eating, Ichirō tells her that she worries too much and that kids are really strong beings moreover that "if they become too spoiled, they lose that original flame". Finding food good, he asks Aiko if she prepared it herself but she tells that it is Rena who taught her. Ichirō replies that "in the village, all the adults and children are very kind", but Aiko add that they are "a bit too generous" and tells him that he "found the scenery he wanted the most" then tells him to "draw a lot of great pictures". He then goes while Aiko asks him where he is going to.
A great view of Hinamizawa is shown while Mion introduces the village to him. She says that 200 000 habitants live here, that the air is thick and that the convenience for transportation is bad nevertheless nobody ever leaves the village. Keiichi asks "Why (どうして・Dooshite ?) ?" and Mion answer.png.pngs obviously that is because everyone loves this village. She tells about flora and says that "the water in Hinamizawa has the best taste in all of Japan". She says that being born here and dying here is the belief of best happiness in this village, making Keiichi emit an "Eeehhhh (えーーー？) ?".
Mion, Keiichi and Rena arrives to a lake, Mion tells to Keiichi that this is the demon mouth. While they pass on the side of the lake, Keiichi tells that "this is pretty large". Mion says that is right and that there is also "a legendary circle here too". Mion asks him if he wants to return her next time because "there is something extremely,interesting here". Keiichi happily agrees but Rena tells them that this place is dangerous and that they aren't allowed to play here but Mion says that she always says things like that. They arrive at a little box, Keiichi asks what is that and Mion answer.png.pngs that "this is a shrine to calm the demons". Rena starts to count a legend whick says that a demon is born in Hinamizawa and tells that is why the lake is named as "the demon's mouth but Keiichi tells that this place feels really good.
By climbing a stair, Mion tells Keiichi that they arrive to "the spiritual guide" of Hinamizawa, the Furude Shrine. While they are climbing it, Mion asks Keiichi to speed up because she finds him really slow, the two girls turn to him, laugh and start to run in the stair, Keiichi who smiles follows 'em. Running, they pass a Japanese portail and arrive at the top. Keiichi tells them that they are too fast and exhauted the girls start to slow, then Keiichi easily joins them and Mion tells him that there's a festivalat the shrine the next Sunday.
They arrive in front of stacks of logs and Mion tells him that because it is his first time here he needs to pray, Rena then agrees but Keiichi tells them that he isn't interested by that kind of thing. Rena tells him that he is obliged to give his greetings to Oyashiro-sama but Keiichi insists that he'll pass on religious things. Rena stops him and insists that if he doesn't give his greeting to Oyashiro-sama he will be cursed, then Mion tells that they says this for his sake, then Keiichi tells them that since he is there he will follow their ways. Keiichi then runs to a sort of religious cauldron, take a sort of ladle but Mion stops him and tells that he needs to do it in order.
