In the extreme environment of Japanese air raids, rampant bandits, and internal strife, how to safely transport No. 91 Aviation gasoline, the lifeblood of China's air supremacy, from the distant Xingxing Gorge in Xinjiang to Lanzhou, the frontline hub of the resistance war.
Zhu Shaoliang, chairman of the Gansu Provincial Government, issued a fatal order to recruit 10,000 camels and 400 carts within a time limit to form a huge transportation team to rush to transport oil. This task is codenamed "Hump". However, the Japanese military spy agency "Lan Agency" has received information and is determined to destroy this lifeline at all costs. The military commanders and central commanders strive to ensure transportation, but at the same time strictly guard against the expansion of influence by the CCP's power. The underground party of the Communist Party of China has a dual mission: to help ensure the smooth flow of the lifeline (in line with the Anti-Japanese National United Front), and in the process to win over the masses, obtain materials, and develop strength. This kicked off an overt and covert struggle in the Gobi Desert and the Hexi Corridor.
