In the bustling streets of Madras, a city where tradition and modernity collide, the story follows Arun Kumar, a man whose early ambition was to probe the darkest corners of the human mind through film. Pressured by family expectations and a lingering fascination with the psychology of the twisted, he trades his camera for a uniform, stepping into the Tamil Nadu Police as a sub‑inspector. The shift from aspiring storyteller to law‑enforcer sets the tone for a narrative that balances curiosity with duty, inviting the audience into a world where every ordinary moment hints at something more unsettling beneath the surface.
Living with his sister Kokila, her husband Doss, and their lively daughter Ammu, Arun finds his new life tangled with domestic expectations. Ammu, eager and mischievous, coaxed him into posing as her father for a harmless school ruse, a gesture that quickly spirals into a series of unforeseen complications. This familial bond grounds the film in heartfelt moments, while also serving as a catalyst that pulls Arun deeper into the city’s concealed tensions. The household dynamics—warm, occasionally chaotic, and filled with quiet humor—contrast sharply with the looming mysteries that begin to surface around them.
Arun’s investigative instincts are further sharpened by his connections at the local school, where he befriends the earnest teacher Viji and her niece Kayal, a child navigating the world with hearing and speech challenges. Their interactions introduce a gentle, humanizing perspective amidst the encroaching gloom, and the school itself becomes a micro‑cosm of the larger urban tapestry—vivid, noisy, and subtly ominous. Through these relationships, the film crafts a mood that oscillates between tender family moments and a growing sense of dread, reflecting the protagonist’s internal conflict between creative curiosity and the responsibilities of his badge.
The atmosphere of Ratsasan is a careful blend of suspenseful intrigue and everyday realism, underscored by the humid cadence of Madras life. As Arun steps further into his role, the audience is invited to share his fascination with the unseen, to wonder what lies hidden in the shadows of familiar places, and to anticipate how his dual passions for storytelling and justice will shape his path forward.
