In a modest house, a wealthy foster uncle and a strict physician keep a young orphan named Amal confined indoors to protect him from the autumn sun and damp air. Despite his illness, Amal sits by his window, fascinated by the bustling life outside and the people passing by on the red road. He talks eagerly to a dairyman, a village watchman, a flower-seller named Sudha, and a group of playing boys, longing to share in their freedom and travel far beyond the distant hills.
The central conflict arises between the restrictive medical wisdom that demands absolute enclosure and Amal's irrepressible yearning for experience and connection. When a new royal post office opens directly across the street, Amal becomes convinced that the King will send him a personal letter. While the adults mock his childish imagination and fear the local authorities, an old man disguised as a fakir encourages Amal's dreams of distant lands like the Parrots' Isle.
As Amal's physical strength fades, his spiritual clarity deepens. The local headman, initially hostile and mocking, eventually brings a blank slip of paper pretending it is the royal missive, prompting Amal to meet the joke with innocent gratitude. This gentle acceptance dissolves the barriers between the boy and his environment.
By the final watch of the night, the King's herald and state physician arrive to announce that the sovereign himself is coming to visit the dying child. Doors and windows are thrown open to the starlight, replacing the stifling confinement with boundless space. Sudha arrives with flowers, leaving a message that she has not forgotten him.
The narrative closes on a note of transcendent release, as Amal slips into a peaceful slumber, confident that the King will grant his ultimate wish to become a royal postman and wander free from door to door.
