Once upon a time in Kolkata there lived a lonely little boy called Tubelight. His daily routine included washing yellow taxis and making them sparkle like pure gold. But where is the twinkle in his lonely life? Love comes to his rescue, the boy falls in love with queen of the night sky - The Moon. With a single minded determination he tries to get hold of this miracle straight from the sky but in vain. Director Shlok Sharma describes the boy's dream world with very poetic pictures. The contrast between these two worlds is reflected by camerawork which oscillates between light and darkness, fast editing, and the use of almost documentary-like commentary.
