What Is Kalamkaval About?

The film is a dark crime thriller that dives deep into the disturbing mind of a serial killer. Mammootty plays one of the most challenging roles of his career, as he portrays a character inspired by real-life criminal cases.

The story follows a sharp and relentless investigation led by a determined police officer, played by Vinayakan, as he tries to decode a series of chilling murders. The film slowly builds tension, focusing on psychology and character depth rather than loud action.
