A researcher’s “suicide” with seemingly flawless evidence forces Tan Yixin, the city bureau’s star detective, and Jin Luoheng, an expert from the provincial department, to become partners.
Tan Yixin trusts her knife-sharp instincts and acts like a blaze, hiding old wounds beneath her irreverent exterior. Jin Luoheng anchors himself in logic and is as cool as ice, keeping everyone at arm’s length to conceal deep-seated trauma. They clash at first sight and can’t stand each other. But the “suicide” scene beneath the hammer is riddled with flaws, and the locked room constructed with fishing line falls apart at the slightest scrutiny. When the evidence points to murder, the victim’s fiancée is soon caught in an “accident,” and a crucial piece of evidence vanishes without a trace. Everything suggests that what they’ve uncovered is only the tip of a massive iceberg.
From ritualistic serial crimes to the tangled secrets of powerful business families, and then to a crisis of trust within the police force... Beneath the lies, a greater conspiracy rises like an abyss. As they repeatedly entrust each other with their lives, reason and instinct spark brilliantly, while ice and fire intertwine to form an unbreakable alliance.
They find in each other the parts they were missing, becoming the only light to reach into the depths of one another’s hearts. When the ultimate truth proves bound up with their pasts and convictions, they decide to turn the tables and lay a trap, using themselves as bait to place the final piece in a game that has lasted for years.
