A mistaken delivery in Mumbai's famously efficient lunchbox delivery system connects Ila, a neglected housewife, to Saajan (Irrfan Khan), a lonely man on the verge of retirement. Through a series of exchanged notes that they pass back and forth through the lunches, Saajan and Ila find comfort in their unexpected friendship. Gradually, their notes become little confessions about their loneliness, memories, regrets, fears, and even small joys. They each discover a new sense of self and find an anchor to hold on to in the big city of Mumbai that so often crushes hopes and dreams. Still strangers physically, Ila and Saajan become lost in their virtual relationship that could jeopardize both their realities.
