All of Us Are Dead EP 9 [ENG SUB]

Gwi-nam attacks the group, but Nam-ra's newfound abilities enable her to once again overpower him and throw him off the roof. At the encampment, Jae-ik reveals information about the cure in Byeong-chan's laptop. Eun-ji goes berserk and bites Chul-soo. She is apprehended and thoroughly examined by researches. They deduce that Eun-ji is a potentially dangerous hybrid of zombie and human characteristics, much like Gwi-nam and Nam-ra. The military dispatches a helicopter to the school, successfully recovering the laptop and preparing to rescue the students. However, the military issues sudden orders to classify all survivors as asymptomatic and abandon them, forcing the helicopter to leave the students behind. A loud thunderstorm ensues, hampering the zombies' ability to hear and smell. Both groups attempt to use this advantage for another escape. The rooftop survivors make their way to the ground floor, where a horrified Cheong-san finds his transformed mother.
