Arko ( Riddhi Sen ) returns to his 'mamarbari' (maternal uncles' house) to meet his extended family. Over there, he meets his second uncle Sujan (Parambrata Chatterjee) who is always locked in a room because of his presumed mental retardedness. Arko takes permission from his grandfather (Soumitra Chatterjee) to allow him to take Sujan out of the house for some time, much to the chargrin of his other uncles (Kushal Chakraborty and Anindya Banerjee) and aunt (Tanusree Chakraborty). As Arko sees his uncle more closely, he realizes that something very wrong has happened to him and the family is hiding a secret. Finally it has been revealed that uncle Sujan is transgender and the family has always wanted to keep this identity shut from outside world. Uncle Sujan commits suicide at the end and donates his eyes to his abusive younger brother (Anindya Banerjee).
