Sirai Story and Plot Overview

Sirai is a crime courtroom and police procedural drama set in the late 1990s and early 2000s. The story follows Kathiravan, an Armed Reserve head constable tasked with escorting prisoners from Vellore Central Prison to Sivagangai Court.

During one such escort, Kathiravan accompanies Abdul Rauf, a young man accused of murder. As the journey progresses, conversations between the cop and the accused reveal disturbing truths about systemic prejudice, wrongful accusations, and institutional bias.
