Exhausted after a grueling day at work, Ham Yegyeong drifts into a light sleep during her chaotic evening subway commute. Her peaceful rest is violently shattered when the man sitting next to her, who had seemingly offered his shoulder for her to lean on, suddenly thrusts his middle finger deep into her private opening. Jolted awake and paralyzed by terror, she can barely squeeze out a desperate whisper: “S-stop, please stop…” The predator only offers a cold, mocking smirk. “Stop what?” “If you stop, I’ll… I’ll just pretend this never happened, aaah!” Yegyeong gasps, her plea cut short as his touch grows even more invasive. To her absolute horror, the nightmare escalates. As she looks up through tears, she realizes that the crowd is shifting, and a group of completely unfamiliar men are slowly closing in, surrounding her seat to seal her fate.
