Based on the heroic battle story of Li Baocheng, Li Baoguo is used as the protagonist to narrate the two "births" of a heroic unit - the first time as an army unit growing up in blood during the Liberation War, the second time as an airborne trooper hardened into steel on the Korean battlefield, and finally finding a new mission in peacetime. The great journey of the Chinese People's Liberation Army from revolutionary war to modernization is reflected through personal destiny.
