The border mission was accidentally exposed, and the lone wolf team led by Zhou Lie was surrounded by enemy forces. When ammunition and food are running out, demolitionist Han Chong transforms the remaining ammunition, and military doctor Su Wan uses the intelligence hidden in the first aid box to piece together an escape route.

But when he stood up from the ashes, he found that Mike had already laid a bigger trap - the real war had just begun.
