Doi of the Maeda Construction Company's Advertising group has little passion for his work. One day the group's leader Asagawa declares, "Let's build the hangar for Mazinger Z!" Having been dragged in by Asagawa, Doi and his co-workers commence putting on appearances of having taken on this request from a fantasy world.

Osamu (Tamaki Hiroshi), a member of the “Ero Supremacy Club,” Kōji (Sato Ryuta), the quiet Biology Club member, and Tatsutoshi (Moriyama Mirai), the solitary Soccer Club member, come across a map one day. Following its markings, they discover a real handgun and three bullets. With the weapon in hand, the three hatch a plan to search for some “truly amazing thing”… Based on the comic Revolver by Maro Naruse & Taiyo Matsumoto, director Takeshi Watanabe (Chaka 2) delivers a youth drama that’s raw, comical, and tinged with melancholy. Following the success of the film Blue Spring (also from Matsumoto’s work), this original video production was created, and in fact, it carries an even stronger Matsumoto flavor. The three leads each stand out vividly, their personalities brought to life in a way that makes this a strangely endearing and memorable gem.
