Vihir is a story of two adolescent boys Sameer and Nachiket (cousins, who are best friends) who struggle with their unconventional outlooks on life and family.

They get to meet after a long time as Sameer with his mother and sister visit Nachiket's village for a family wedding.

Sameer and Nachiket both observe people in the house and try to understand their behaviour as they are not used to complexity of family relationships.

His journey takes him by a train to a stone quarry where he meets one nomadic sheep herder.

The shepherd shares his life experience with him when he was little about a lost lamb and how he finds it with the eyes of his heart.
