In June 1950, a war between North and South Korea broke out, and it quickly engulfed the entire peninsula. A South Korean soldier (Kim Seung Woo) is ordered to take his troops to assist a group of young soldiers defend an area near the Nakdong River. The ragtag group of inexperienced soldiers, which includes criminal bad boy Gap Su (Kwon Sang Woo), is led by Jang Beom (T.O.P), the only one in the group with battle experience. After providing minimal training to the youth squadron, the expert soldiers go off to the Nakdong River to fight the North Koreans. However, the enemy battalion, led by General Park (Cha Seung Won), decided to take an alternate path in the direction of Jang Beom's squad.
