Platoon Two encounter prisoners at the Yongwon Penitentiary. Since there are no prison guards, they have been locked up without any food supplies for a while now, and they threaten the kids to open the cell doors. One of the prisoners hands over a photo of his mother and begs Ae-seol to contact her for him. Meanwhile, at Yongdu Service Area, intruders barge in and look around the place.
