Arko, affectionately called Posto (Arghya Basu Roy), is a little boy raised by his grandparents --- Dinen Lahiri (Soumitra Chatterjee) and Gouri Lahiri (Lily Chakraborty) --- in Santiniketan. His parents, Arnab Lahiri (Jisshu Sengupta) and Sushmita Lahiri (Mimi Chakraborty), are both settled in Kolkata. They only visit their son once on the weekend. A clash between the grandparents and parents begins when the latter want to take away the child as the father gets an offer to start a restaurant business abroad. The relationship between the parents of Posto and his grandparents, which eventually sours, drags the kid into the courtroom.
