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!
