Naachiyaar (Jyothika) is a straightforward cop who is not only known for
her violent interrogation but also for insubordination towards her
higher officials. Her plan to go for a foreign tour with her family is
disrupted by a sensitive case which involves a slum dwelling minor girl
Arasi (Debutante Ivana) and her lover Kaathu (GVP) which leads the
latter to be jailed. What is the crime Kaathu committed and how
Naachiyaar deals with the case and whether justice is upheld forms the
rest of the screenplay.
