Slender and demure office lady Chihiro is constantly targeted by molesters during her daily commute. One morning, reaching her breaking point, she tries to stop a groper by grabbing his hand, only to be surrounded by the man's accomplices. Helpless against their advances, their violating hands close in relentlessly. Semen shot from a penis exposed from his pants splatters onto Chihiro's skirt, further humiliating and cornering her. Determined to escape, she resolves to quit her job—but then her boss, having heard rumors of the assaults, invites her into a lesbian encounter. Carried by this momentum, the company president hires yakuza thugs to escalate the molestation, dragging Chihiro deeper into a nightmare that consumes her entire life.
