[3] During the Korean War, a squad of Marines from the South battle Chinese forces in the North, and are killed off one by one.

At the beginning of the film, a young girl Young-hui and her mother desperately try to run for their lives from the Chinese soldiers.

The girl's mother is shot dead but soldiers rescue Young-Hui in time and they immediately hide her from their higher-ranking commanders.

The first half of the film centers on the Marines focusing on entertainment and looking after the young girl to alleviate the burden of the war.

Afterwards, the Marines depart Young-Hui and head to the mountains to go into heated combat to confront the People's Volunteer Army.
