Duty After School Part 2
The students of Sungjin High School Grade 3 Class 2 are now reservists and roam the city to destroy the deadly spheres that drop from the sky. Some of the reservists are driven by the promise of receiving bonus points on their CSAT exams for their military service, while other reservists are simply waiting to go home. Now, their radio has mysteriously stopped working, which makes it impossible for them to communicate with the military's command center. The reservists make the fateful decision to separate into teams and search the Yongwon Metropolitan Hospital and Yongwon Penitentiary for supplies. Kim Chi-Yeol (Kim Ki-Hae) observes his fellow reservists with his camcorder.
