The film alternates between two stories( one shown in black and white, and the other in colour): One’s about Vasanth( Aari), an artist, who learns about a forest called Mayavanam, and how it was once home to a mental asylum, in which patients — one among them, Maya Mathews — were used as guinea pigs for horrific scientific experiment; and the other’s about Apsara( Nayanthara), an orphan mother of a one-year-old baby, and an actress struggling to make ends meet. As is the case with such films, both stories eventually converge at a point.
Right at the very beginning, there’s a scene that’s constructed very differently from what we are usually used to seeing. Apsara, through her friend( Lakshmi Priyaa), gets an opportunity to show her acting mettle to the director of a horror film. The director tells her that the situation is about a pregnant woman poisoning her husband after learning about his infidelity. While another movie would probably have had Apsara crying her heart out or making a spiteful speech upon the body of her husband, she underplays it; and not unconvincingly as Siddharth does in Kaaviya Thalaivan in a similar scene. Apsara radiates gloom throughout the film, and is key in retaining the sombre atmosphere throughout the film.
