ACP Antony Moses (Prithviraj) manages to track down his friend's killer but suffers partial memory loss in a near-fatal accident right after. He is then forced to re-investigate the same murder to recover his lost clues.

Stylistically, Mumbai Police South is a hybrid: classic noir shadows and modern procedural pacing. The director’s camera loves corridors — police station hallways, hospital passages, and glass-fronted interrogation rooms where the light slices faces into evidence and doubt. Cinematography and sound design are as much characters as the actors: rain on tar, the nervous tick of a wristwatch, the echo of boots on tile. The Hindi dubbing’s pacing must respect those sonic beats; mis-timing dialogue can flatten tension, while well-timed lines heighten it.
