Binhai City, a modern city with flashing neon lights, conceals the turbulent undercurrent of the overseas intelligence force "Viper". Special Forces Captain Long Yu, burdened with the past pain of border anti-terrorism, uses the "Blade" Special Forces as a shield to protect the city's military and intelligence security. Bai Yuhan, an intelligence analyst of the National Security Bureau, studied under the guidance of the old National Security Bureau. With his meticulous thinking and keen insight, he became a sharp sword that tears through the darkness.
The two met again because of a joint operation to arrest overseas intelligence traffickers. The glimpse of the National University of Defense Technology seven years ago turned into a tacit understanding of fighting side by side in the smoke-filled mission. From secret tracking in the financial center, to close confrontations in flea markets, to thrilling raids in abandoned factories, they gradually dismantled the intelligence nodes of "Viper" in Binhai City. Unexpectedly, its mastermind "Scorpion" absconded with the core intelligence of the military exercise, and even planned a bomb attack plot at Binhai Port.
The righteousness of the family and the country comes first, and the love between children grows up on the side. In the life-and-death tests, Long Yu and Bai Yuhan not only have to engage in the ultimate game of wisdom and force with foreign forces to protect national military secrets and urban security, but also let the deep-seated feelings grow quietly in the intertwining of gunpowder smoke and neon lights. When the sharp blades are unsheathed and on the Dragon City, they use loyalty as their bones and love as their wings, writing a chapter of iron-blooded responsibility and tenderness that belongs to Chinese soldiers.
