A mistaken delivery in Mumbai's famously efficient lunchbox delivery system (Mumbai's Dabbawallahs) connects a young housewife to a stranger in the dusk of his life. They build a fantasy world together through notes in the lunchbox. Gradually, this fantasy threatens to overwhelm their reality.

The human drama is based on an interesting premise of a seasoned character actor who decides to come out of retirement and begin a quest for a record of some sorts, that elusive 500th role, the one for which he shall be remembered forever.
