Raam

Ramakrishnan, known as Raam, is a young man grappling with social and emotional challenges. He harbors an intense love for his mother Saradha, which drives many of his actions and makes him a suspect in her murder. His behavior is later linked to autism, shaping how he interprets danger and responds to conflict. Despite skepticism from others, Raam seeks justice and faces the consequences of his choices.

Saradha is Raam's mother, a central figure whose protective instincts clash with the peril surrounding her. Her murder triggers the investigation and exposes the town's hidden ties. She is loving and caring, yet her circumstances entangle Raam in a web of trouble.

Inspector Umar leads the investigation with steady, methodical resolve. He questions Raam and his circle, gradually uncovering motives and secrets. His pursuit of truth is tempered by the complexities of family loyalties and community judgments.

Sub-Inspector Malaichamy is Raam's neighbor, a lawman whose family ties intersect with the case. His daughter, Karthikaayini, is drawn to Raam, adding a personal dimension to the investigation.

Satish is Karthikaayini's brother, a troubled young man whose fear of exposure leads to Saradha's murder. His drug addiction and panic drive a desperate act, and he ultimately confronts Raam and the investigators.

Karthikaayini, Malaichamy's daughter and Raam's neighbor, is drawn to Raam. Her presence adds romantic tension and complicates the emotional landscape of the investigation.

Vaazhavandhan appears as a local figure in the town, part of the network of people connected to Raam and the case. The film uses his interactions to enrich the sense of community and hidden motives.

The psychiatrist character appears in Raam's life as a clinician who assesses his mental health and behavior, offering insights into his emotional state and the family's dynamics.
