He is escorted to a high security prison complex in Chennai by Macaulay (Shaam), an honest, law abiding police officer who is given the charge of monitoring him until his execution. The prison provides freedom to all prisoners, including Balu, to do whatever they want, as long as they do not cause unrest.
