Asami, an aspiring idol high school student, is frequently taken out by an acquaintance older man who always carries a video camera and insists on filming her. Though Asami resists at first, the man convinces her by claiming it's a "camera test for becoming an idol." The filming gradually escalates as he begins teaching Asami adult games, eventually moving into gonzo-style sex scenes, capturing her youthful, undeveloped body and embarrassed reactions in vivid detail. The footage authentically portrays Asami's pure emotions and innocent demeanor.
