In 1942, the military's ace agent Shen Zhining was falsely accused of treason and thrown into a secret prison that he had participated in designing.
In the dark dungeon, she reunited with Huo Yanting, the "treasonous" marshal she had captured three years ago.
Her former mortal enemy became a prisoner next door. What's even more ironic is that the person interrogating her was actually her childhood sweetheart Lu Chenfeng.
Unwilling to wait for death, Shen Zhining and Huo Yanting put aside their past feud and jointly planned a thrilling prison escape.
On the way to escape, there were murderous plots step by step. From being wary of each other to trusting each other in life and death, the two men worked together to tear apart the biggest treasonous conspiracy within the military.
Under the flames of war between their home and country, they found each other in the desperate situation of adhering to their faith. In the end, they exchanged blood and fire for their innocence, and spent the rest of their lives in the smoke of troubled times.
