1948, Dusk in Jinling. Lin Zhiyuan, the ace pilot of the Kuomintang, returned to the country after studying with the ideal of serving the country. What greeted him was not glory, but the ruthlessness of the civil war and the corruption of the officialdom. A bombing mission directed at his compatriots became the last straw that crushed his faith.
On the ground, the beacon of his soul - Jinling University female student Shen Wangshu, is gentle but firm. There is a flame of progress hidden in her books, and an undercurrent of protection surges under her love. When the underground party extended an olive branch, a "dawn uprising" with life as a bet was quietly planned in the dark night.
From delivering the first intelligence to planning the route under strict surveillance, every heartbeat is an alarm and every look requires a password. When loyalty is scrutinized, when close friends are doubted, when the shadow of spies is covered under the plane tree of love, the fate of Lin Zhiyuan and Shen Wangshu undergoes the ultimate test in the fire of trust and sacrifice.
He will pilot the heavy B-24 bomber to tear through the tightly blocked sky. She will pave the last way for him to survive in the crisis-ridden city of Nanjing. This is a shocking retrograde march toward dawn, and it is also a romantic song composed by a pair of lovers using faith and love in the darkest moment of history.
