In 2025, Lu Chenzhou, who has dual identities as a military doctor and a special operations team member, was suddenly hit by a thunderstorm during earthquake rescue. He actually traveled to the eve of the Songhu Battle in 1937 and possessed a seriously injured military health soldier. In this war-torn land, he met Gu Wanqing, an underground party military doctor. The two used their medical skills to save lives and heal the wounded in the flames of war, and devoted themselves to the cause of anti-Japanese and national salvation. From the emergency rescue on the Songhu battlefield to the secret cooperation in the Suzhou clinic; from the construction of the medical system in the Shanxi-Chahar-Hebei base area to the thrilling lurking in the enemy-occupied Shanghai... They rely on modern medical knowledge and wisdom to protect lives and fight against aggression in life-and-death tests. As the victory of the Anti-Japanese War approaches, cracks in time and space appear. Lu Chenzhou faces the decision of whether to return to modern times. How will this special bond spanning time and space continue?
