The film tells the story of hundreds of people who were left alien in their own land, due to lack of documents to prove themselves and their identity. Mohanlal's character in the film as eighty-year old character Valiyakathu Moosa, son of a freedom fighter, is a representative of such people. To the Indian government he is a Pakistani, and to the Pakistani government he is an Indian. Mohanlal added that there are a lot of people like Moosa in Malappuram district of Kerala, who still hold their Pakistani passports, even though they have come back from there in the 60's.

Valiyakathu Moosa is one of hundreds of Malayalees who left to work in Karachi during the days of the British Raj, who after independence returned to India in the 1960s and settled in Malappuram. They do not have a passport or even an address in the land they were born in, due to their plight in Pakistan during the time of separation and independence. Moosa has a wife and children here who are Indian citizens, but Moosa himself is not considered a citizen of the country, due to some technical objections from the bureaucracy.

Mohanlal is playing one of the toughest roles in his career. His character Valiyakathu Moosa in the film has four periods, from 35 to 90 years. In every period Mohanlal is shown with different looks. The 90 year old Moosa's shots were shot in the Pakistan borders. The film also moves through many stages back and forth as flashbacks to present the story of Moosa. Lakshmi Gopalswamy plays the role of his wife. Kavya Madhavan comes up in the role of a journalist investigating into life and livelihood of this sidelined section of society.

The film is produced by Antony Perumbaavoor in a new banner A and A productions. The film with music done by Ramesh Narayan and Shahsaad Aman will have three songs sung by M G Sreekumar, Vineeth Srinivasan, Chitra and Sujatha.
