The film is the sixth movie in director Jayaraj's "Navarasa Series".

The story is set in Kuttanad and its backwaters in central Kerala during the World War II and revolves around a postman, who delivers money orders at homes of those who have joined the army.

The film was praised by the critics for acting performance of the lead (Panicker), the production design, and cinematography. The Times of India, giving a rating of four starts out of five, called the film "a stunningly crafted poetic story of a postman and a land that is stricken by the fear of death".
