Cheng Nian was ordered to approach Zhou Mu, an ancient painting appraiser who lived in seclusion in Nanshan, to investigate his suspicion of "treason." She used love as bait to weave a gentle trap, but she didn't know that she was walking into a bigger situation step by step. When the sound of gunshots broke the tranquility of Nanshan, Zhou Mu blocked the fatal blow for her and whispered on the verge of death: "Falling in love with you is the only truth... In my scene."
Only then did Cheng Nian discover that what Zhou Mu was guarding was not evidence of crime, but a blood-stained list, linked to the lives of countless potential comrades. And the blade she handed out was inserted right into the hero's heart. Between lies and truth, mission and personal love, they must make a choice: continue to be at the mercy of fate, or join forces to fight a bloody road to dawn and love in a deadlock?
