In the 1980s, the anti-gang campaign swept through the small town.
Jiang Qinglang is an upright young detective who comes from a middle-class family. He has bright eyes and a bright heart.
Frost Blade is a personal killer who has been raised by the underworld boss for many years. He grew up on the tip of a knife and is cold-blooded and silent.
One policeman and one gangster, one light and one dark,
In the pursuits, confrontations, and brushes with life and death,
Giving birth to the most taboo and unspeakable feelings.
When the sun breaks into the darkness, when the sharp blade meets the true heart,
Justice and sin, loyalty and love, will eventually confront each other.
Their story, from the beginning, had no way out.
