Hareendranath Nair (Prithviraj) is an Indian who is assigned to guard an Indian Picket ( i.e., Picket 43) in Kashmir. It was said to be a very dangerous place, and Hareendran had to be forced to take charge at the place, forsaking his sanctioned leave due to the forcefulness of his superior officer (Renji Panicker). Hareendran is forced to stay at the Picket with an extremely trained dog called Baccardi as his companion. He starts seeing the dog akin to someone with intelligence and treats him like a person, not even permitting anyone to call Baccardi a 'dog'. Hareendran confides in the dog his inner thoughts and emotions, which lifts his spirit slightly even at the most difficult times.
