Dinanath, Roshan Mathew, is a rookie cop whose inexperience often clashes with the seasoned Sub-Inspector Yohannan, Dileesh Pothan, as they patrol the city through the night. Together they respond to a string of troubling cases that test their limits: a suicide case that suggests there is more beneath the surface, a mentally unstable man who turns violent and terrorizes neighbors, incidents of domestic violence, and the delicate matter of a girl from a wealthy family who elopes with a boy from a poorer background. The nights are long, and each scene paints a picture of a city where danger, rumor, and personal history collide.
Dinanath carries a heavy personal burden. His father died by suicide, a trauma that shadows his every decision and heightens his emotional reactions in the line of duty. Yohannan, on the other hand, has his own weight to bear—his wife suffered a stillbirth, leaving him as the sole caregiver and adding a quiet gravity to his actions. He is a veteran, and his experience offers a steadier hand, yet he remains both frustrated and amused by Dinanath’s inexperience, guiding him while also watching him stumble and learn in real time.
As the investigation unfolds, the pair confronts not only crime but the fault lines of class and power. The wealthy and influential family involved in the girl’s elopement becomes entangled in a cover-up, and the investigation takes a darker turn when one of the daughter’s boyfriend’s friends is killed. The culpable party appears to be connected to the family, and the relationship between power and protection casts a long shadow over the case. In a cruel twist, the high-stakes cover-up leads to Dinanath and Yohannan being framed for murder by someone close to the powerful family, a superior who seems to be playing a dangerous game.
Dinanath’s fear and panic peak during his arrest, and he makes a desperate move to escape, a moment that ends in tragedy when he is struck by a truck and dies instantly. The loss is a devastating blow for Yohannan, who vows to fight for his partner’s innocence and to seek the truth in the face of mounting pressure. The film closes on a note of resolve, with Yohannan preparing to pursue justice in court, driven by loyalty, duty, and the haunting memory of what happened that night.
Ronth builds its mood through nocturnal cityscapes, close-up reveals of fear and determination, and a careful balance between duty and grief. The friendship between the two officers is tested by professional stakes and personal pain, and the narrative threads come together to explore how trauma shapes judgment, how corruption strains integrity, and how the pursuit of truth persists even when the system seems intent on burying it. The characters’ humanity remains at the center, and their ethical choices echo long after the final siren fades.
