Police constables Balagopal and Jolly Kurien have been at odds for years, yet they’re pressed into a high-stakes transfer: two prisoners, Nandu and Maran, are to be moved from Kannur to Trivandrum aboard the Parasuram Express. The journey starts with a tense dynamic between the two officers and their cuffs, but fate spices the ride when a planned orderly handover spirals into chaos at Kayamkulam station: [Nandu] escapes. In a race against time, Balagopal and Jolly step off the moving train with [Maran] in tow, all while frantically searching for the runaway inmate who holds a dangerous secret.
What unfolds is the unraveling backstory of [Nandu], revealed through the uneasy alliance of three unlikely allies, the trio who would come to be known as the musketeers of this tale. The threads begin with a troubling familial history: [Nandu]'s father, Narayanan, has long harbored a wrongful fixation on Lakshmi, Nandu’s sister. Lakshmi is the daughter of Nandu’s mother and her former husband, making her a half-sister and not a daughter of Narayanan. The revelation deepens the stakes, as Nandu grows determined to end Narayanan’s influence once and for all. In a moment of desperation, he hatches a plan to kill his father, but the trap backfires in a heartbreaking twist—the very scheme intended for Narayanan results in the accidental murder of his mother, sending Nandu spiraling into custody on a murder charge.
The plot thickens as Narayanan sneaks a visit to the jail and reveals a carefully staged persona of reform, performed for Lakshmi to soothe any doubts about his character. This revelation plants a seed of revenge and a fierce resolve in Nandu, who cannot ignore the layered deceit that binds his fate to his father. With the truth loose and danger mounting, Nandu escapes whenever possible, drawing the attention—and the sympathy—of the three musketeers who’ve begun to see the human cost behind the feud.
As the pursuit intensifies, the musketeers collide with Narayanan as both sides move toward a deadly confrontation. The tension culminates when Narayanan tries to strangle Nandu with his own handcuffs, only to be thwarted by Jolly, whose intervention results in Narayanan’s death. Balagopal contemplates reporting Jolly’s actions to the authorities, but Nandu steps forward, choosing to bear the blame himself to honor a larger mission and to protect Jolly from a worse fate. Maaran, sensing the layered truth behind the saga, proposes a plan to keep the truth buried, and the others agree to see it through.
That night, Narayanan’s corpse is laid to rest in a nearby church cemetery, slipping quietly into the earth beneath the shadows of the town. In the days that follow, the film closes on a note of uneasy karmic balance: each character appears to find a form of peace or acceptance in the aftermath of a harrowing sequence of choices, where loyalty, vengeance, and forgiveness intertwine to shape their fates. The story, carried forward by the intertwined motives of law, love, and retribution, leaves the audience with a stark reminder that every action carries a consequence, and in the end, the home they seek may be found in the quiet aftermath of a storm.
