Masilamani, a middle-aged man who works as a security guard at a popular sports and recreation club, is being questioned as a murder suspect while his terminally ill young son waits outside the investigation room. An eccentric Masilamani goes back-and-forth in his story in a non-linear manner when he talks about the disappearance of his wife and the murders of her illegitimate affairs. His mysterious fashion of speaking and his odd nurturing side confuses the police officers who try to dig into his history and struggle to find a solid evidence that connects him to the murders.
