On a crowded commuter train, schoolgirl "Miu" becomes the victim of a vicious molester. As she screams, "No, stop it!" no one comes to her aid—instead, the predator brutally thrusts his cock into her again and again. While desperately pleading for help, a stalker watches the entire assault unfold, then launches a surprise attack. He drags her to an abandoned factory where he inflicts further violence, leaving her unconscious and collapsed on the ground. Soon, another man appears, followed by more, subjecting her to three consecutive rapes and deep-throating her until she drools uncontrollably, sobbing in agony. Sacrificed and degraded, she's reduced to a beast-like sex slave. Each cry for help only excites her attackers more, driving her deeper into despair and plunging her into an inescapable abyss.
