[6] Karuppu Durai, an 80-year-old man, bedridden for the past three months in a coma, suddenly wakes up one fine day to overhear his family planning to kill him by performing an ancient euthanasia or thalaikoothal ritual.

Thus begins an eventful road trip of this unlikely pair – an old man running away from his family and a young boy who never had one.
