The story begins when four schoolgirls who met at a tutoring school lose their phones. The lost phones contain all their personal information, including home addresses, private activities, and daily routines. The man who finds the phones uses this data to sneak into the girls' homes and then abducts and confines them in an abandoned building. Without mercy, he assaults the schoolgirls one after another, giving them no chance to resist. He repeatedly subjects them to rape, deep throat, choking, and spanking. One by one, they are violated with creampie and facial cumshots, their terror unending.
