A Malayalam-language film that depicts the plight of impoverished Indians seeking jobs in the Middle East has been drawing throngs to cinemas.

Aadujeevitham (Goat Life), adapted from the bestselling 2008 Malayalam book, stars Prithviraj Sukumaran as Najeeb, an Indian immigrant in Saudi Arabia who is kidnapped and forced into slave-like labour as a goat herder in the desert. The story is inspired by the real-life ordeal of a man with the same name, who was abducted in the country in the 1990s and managed to escape after two years.

Written as a gripping thriller, the book has become a cultural cornerstone in the southern Kerala state, with its 250th edition released this year. Its widespread acclaim had sparked a conversation on the harsh realities of migrant life in the Gulf.

The three-hour film has also done exceedingly well, grossing over 870 million rupees (£8.23m, $10.4m) worldwide in the first week of its release. Critics have called it a “stunning survival drama” and a much awaited “cinematic portrayal of brutal struggle”.

Aadujeevitham shows Najeeb isolated from the world, alone with his master and his animals, facing extreme heat in a harsh desert, miles away from the nearest road, with no access to a phone, paper or pen to write with, and no one to call a friend. He drinks water from the same trough as his animals.
