Towards the end of the Korean War, a South Korean battalion is fiercely battling over a hill on the front line border against the North in order to capture a strategic point that would determine the new border between the two nations. The ownership of this small patch of land would swap multiple times each day.
Kang is dispatched to the front line in order to investigate a mysterious death, but gets spiralled into the terrifying face of war when he meets his friend Kim, who has transformed into a war machine, along with the rest of his unit. As the countdown for ceasefire begins, both sides become more vicious as the stakes rise until the very last man is left standing to claim the hill.
