Dark Night Patrol Line

A gun was lost overnight, and the whole city was undercover. Before daybreak, he must retrieve the gun—— Because every bullet may change a person's fate. Hong Kong city, late at night. Anti-gangster police chief "Fat Ma" was attacked in a back alley of a night market and his gun was stolen. For police officers, missing a gun is a capital offense. MPU (Mobile Patrol Unit) Sergeant Lin Zhengfeng was ordered to find the missing gun before dawn. He is calm, decisive and walks on the edge of the rules. He is known as "Black Boy". The female police chief Guo Kaiqing who partners with him is rigorous and upright, but gradually discovers that there is an unknown secret hidden behind Lin Zhengfeng. During the pursuit, every clue points to a deeper whirlpool. And when an old photo was sent via an anonymous text message, and the figure of Lin Zhengfeng's late father suddenly appeared in the photo, he realized that this missing gun case was just the tip of the iceberg. Fifteen years ago, my father fell to his death in mysterious circumstances, which was deemed a "suicide." Now, gunfire rang out again. One night. One shot. An unspeakable truth. Who will fall into the abyss before dawn?
