The urban legend spreading on social media, "Pigpen." Popular underground idol Arisu suddenly disappears. Her whereabouts lead to PLANT, a place that brainwashes humans and treats them as livestock. Torn from her idol image, Arisu is forced to dance naked while subjected to water torture. As tears stream down her face, she's repeatedly assaulted with deep throat and suspended bondage, followed by creampie-filled fellatio. Even when battered and broken, Arisu attempts escape—only to be captured once again. Restrained tightly, her vagina is tortured with a metal bat, driving her to the brink of madness, before another man's cock violently penetrates her.
