Ten years ago, 24-year-old criminal policeman Yu Zhenge broke into a fire scene alone during an explosion and rescued eight hostages. Due to serious injuries, he retired from the front line and became a portraitist of the Criminal Investigation Detachment, continuing to solve cases in another way.
Ten years later, the new criminal investigation detachment captain Li Muyun was parachuted into the post.
The two gradually got closer while cooperating on the case, but neither of them knew that in the crowd outside the fire scene ten years ago, there was a pair of eyes, through the thick smoke and fire, looking from a distance at the figure who rushed out of the explosion with a child in his arms.

The nightmare that he thought was over long ago turned out to contain an undiscovered truth...
Intention: Some people are a miracle alive.
