Medical student Lu Ji vowed to become a special police officer because of his powerlessness and cowardice when his mother was attacked. He joined the special police training camp "Steel Thorn" and met seven companions with different backgrounds, including traffic policeman Long Yue and genius sniper Tang Xiao. Under the rigorous training of "King of Guns" instructor Dai Gao, everyone supported each other and went through many hardships.
Not only did they pass brutal selection, but they also won the honor of national and international special operations soldier king. Jiang Xiaoyun stood out and succeeded Dai Gao as the new gun king. In the end, this group of passionate young people formed the "Red Eagle Brigade", transformed through life and death missions, and grew into a sharp blade that frightened terrorists, guarding the peace of the motherland and the people with loyalty and blood.
