Soo-ho, who leaves the dormitory, begins to secretly move again. Meanwhile, Lee Kang-moo secures decisive evidence of Soo-ho's whereabouts and pursues him.

Soo-ho negotiates with the head of the National Security Agency to escape the dormitory with his teammates.

Turning a blind eye to Yeong-ro who feels betrayed, Soo-ho continues the hostage crisis, and a doctor, Kang Chung-ya, is sent in to treat an injured associate of Soo-ho.
