A mistaken delivery in Mumbai's famously efficient lunchbox delivery system connects a young housewife to an older man in the dusk of his life as they build a fantasy world together through notes in the lunchbox. Middle class housewife Ila (Nimrat Kaur) is trying once again to add some spice to her marriage, this time through her cooking. She desperately hopes that a new recipe will finally arouse some kind of reaction from her neglectful husband.
Five-year-old Saroo (Sunny Pawar) gets lost on a train traveling away from his home and family. Frightened and bewildered, he ends up thousands miles away, in classic Kolkata. Somehow he survives living on the streets, escaping all sorts of terrors and close calls in the process, before ending up in an orphanage that is itself not exactly a safe haven. Eventually Saroo is adopted by an Australian couple (Nicole Kidman and David Wenham), and finds love and security as he grows up in Hobart.
