During a torrential downpour, barista Cheng Yuqing is in a car accident and rescued by the mysterious surgeon Xu Chen. She has no idea their encounter will uncover a bloody secret from twenty years ago: her father, a special forces soldier, did not die in a car accident. He was silenced for exposing a top-secret military project called “Silence.”
When Cheng Yuqing discovers the encrypted evidence her father left behind, danger closes in: a robbery at the coffee shop, a nighttime pursuit, files rifled through... The unhealed battle scars on Xu Chen and the military medals in his drawer hint at his deep connection to the secret. While fleeing together, they discover that Xu Chen’s father and Cheng’s father were comrades, and that he too died in a supposed “accident.”
“The safest place is behind someone else’s eyes.” The riddle her father left behind guides them to the truth hidden in a compartment in a surveillance camera. A senior Defense Ministry official, a biochemist, and a mysterious agent emerge one after another, while the formula for the antidote is hidden in Cheng Yuqing’s genetic code.
When Xu Chen’s identity becomes a mystery, Cheng Yuqing must decide: is he her protector or part of the conspiracy? Amid gunfire and lies, the two of them, both scarred and battered, save each other. He teaches her to use a gun; she teaches him the meaning of lily of the valley. He stands like a statue in the rain at night; she searches the ruins for a glimmer of light.
If their meeting was planned, could their love be instinctive?
When the truth wounds more deeply than bullets, can a wire ring hold their trust together?
