Ottaal (2014)

Kuttappayi, a young boy, is miserable and desperate as he starts writing a letter to his grandfather from a place, dim and dark. Kuttappayi's recollections takes us to the picturesque locations of Kuttanad, where Kuttappayi and his grandpa, Valiyappachayi, are arriving with their ducks. The village is as pleasant as it can be even though what brings him there is the death of his dearest parents. With hope and freedom, he is about to start his life afresh among the village's letter-less postman, the nameless dog, the rich lad, Tinku and many more.
