In 1942, Japanese air raids ravaged the rear area. Qin Chenchen, an engineer returning from overseas, was tasked with building a secret military factory deep in the Loess Plateau. His first encounter with Jin Yiying, a field nurse, was a bicker—he found her "overly worried," she called him "death-defying."

They raced against time, outwitted enemy spies, and quietly fell in love. Until the factory’s test run day, a Japanese reconnaissance plane locked on. Qin gave Jin the last air-raid shelter ticket and rushed to the machines.
