Sypnosis:

The four brothers of the anti-drug team—Tai Hua, Lao Mi, A Feng, and A Tang—once participated in a mission to capture the drug lord "Old Dad." Before the operation, they handed in their phones to prevent eavesdropping. However, due to a corrupt cop’s betrayal, they fell into a trap. A Feng was killed, Inspector Lu also lost his life, and A Tang disappeared, leaving tension between Tai Hua and Lao Mi. To uncover the truth and destroy the drug cartel, the two went their separate ways, struggling between loyalty and betrayal, justice and evil. Amid internal conflicts, the battle for justice faces an uncertain fate.
