Jiang Zhi, a former sniper of the "Falcon" anti-narcotics team, returned with a gunshot wound to his shoulder blade and joined the crime team "Dingfeng". The team leader Lu Chenyu is his former Falcon deputy - Leng Rushuangxue. The old explosive wound on his waist and Jiang Zhi's gunshot wound are both scars left in the dark night. Arms half-frozen in liquid nitrogen and incubators engraved with "L" drag this group of "nails in the wind" with special skills into a puzzle: the sniper scope locks the evil, and the pain of old injuries wraps up the past of the Falcon team. They use bones as blades and blood as nails to restart the Falcon's edge in the frost wind and guard the light in the morning mist.
Purpose: Using the intertwining of anti-drug and criminal investigation to write the inheritance of faith and redemption in the dark night of the "Falcon" team
