Bloody oil paint soaks into the canvas, and the death art exhibition begins.
Criminal investigation captain Zhao Chen stepped into the scene of the murder and discovered that female painter Lin Wan's final paintings were painted with blood.
A series of murders are hidden deep in the brushstrokes, and twelve strange paintings predict a countdown to death.
The elites of the task force each have their own unique skills: the criminal profiler cuts through the twisted desires, the trace expert holds the barrel of the murderer's throat, but the mysterious collector launches a hunting net in the dark.
When the female reporter breaks into the restricted area, when the betrayer tears open the evidence bag, when the most trusted partner stops breathing in his arms.
As the bloody mystery continues, Zhao Chen must decipher this art of killing that uses human life as the paint - and the murderer's brush is completing the final stroke in a corner that he cannot see.
