"What you love is the moonlight, and I am the one who steals fire for you in the dark night."
Twenty years in China, a pursuit and an escaped marriage brought two women with similar looks together on a rainy night.
Shen Qingyue, a shady illegitimate daughter, is the sharpest blade of the underground intelligence network. Su Wanqing, the jewel in the brocade, is a progressive journalist who holds a pen and yearns for freedom. A substitute contract roughly sewn their fates together - Qingyue replaced Wan Qing and stepped into the mansion of the iron-blooded marshal Gu Yushen to carry out the most dangerous task in her life: to steal secrets or make him fall in love.
Gu Yushen soon discovered that this "fiancée" was completely different from the naive and arrogant rich girl he investigated. She was calm and mysterious, with pain and sparks in her eyes that he couldn't understand. Knowing that it was a play, he got deeper and deeper step by step, trying to catch the elusive shadow in the conspiracy and smoke.
The real Wan Qing is on another battlefield, side by side with the mysterious banker Lu Wenzhao, using paper and pen as a gun to uncover the scars of the times. When the war breaks out and the country is overturned, their identities are finally pushed to the edge of the cliff.
The substitute game in the past has evolved into a life-and-death game and belief choice between four people in the war-torn times. Should you continue to act like someone else, or should you find yourself again? Indulge in small love, or melt life into the broader mountains and rivers?
When the two moons break through the fog and complement each other, what they illuminate is not only a deep-seated love, but also a nation's path to nirvana in blood and fire, and the astonishing transformation of two women from "subordinate" to "dominator".
