Midori Asakusa is a first year high school student who dreams of creating her own animation. When she visits a screening event held by Anime Club with fellow student Sayaka Kanamori, an amateur model Tsubasa Mizusaki starts talking to them. As she was being chased by men dressed in all black, Asakusa and Kanamori help her get rid of them. To their surprise, they learn that Mizusaki is also aspiring to be an animator. The three of them hit it off to realize their own "Incredible World" together!

As Mizusaki is banned from joining the anime club by her parents, the only way for the three of them to make anime is to set up a new club. At the staff room, their teacher tells them that they will be granted a certain budget if the objective of their club was to create a live-action movie. Kanamori suggest that they will call their club "Eizou (Film) club" and use its name as a disguise. Thus "Eizou-ken" came into existence! They head off to a storage space previously used by the anime club and realized all kinds of treasures behind the door!

The student council's budget committee looms on the horizon as the eizouken's project is still far from finished. As Mizusaki struggles with effects shots, Kanamori reminds her of the grim reality of the approaching deadline. While Asakusa manages to extend their run-time with creative use of existing art, the club is forced to make hard decisions about what parts of their creative vision to sacrifice and which parts to preserve. But even then, will they have something that resembles a complete product in time?

Asakusa discovers a mysterious robot, and before long Mizusaki and Kanamori are implicated in the conspiracy surrounding it. The nature of that insidious plot? The Shibahama High School robot club commissioning an anime short from the eizouken. After exploring the maintenance tunnels beneath the school, the girls have their first production meeting with the robot club, where they run into the complicated contradictions in the visions of their would-be clients.
