In Mumbai, office workers don’t pop round to their local Pret at lunchtime. Instead, they benefit from the astonishing system of dabbawalas, 4,000 of whom collect and deliver 160,000 packed lunches every day through the bustling city. The lunchboxes are carried by bike and train into the centre of Bombay and delivered promptly to the workers’ desks just in time for the lunch break; then, after lunch, the empty tins are packed away and carried home again. Stay-at-home housewives take pride in sending off a home-cooked lunch for their children or husbands; while even unmarried office workers receive lunchboxes courtesy of services offered by local restaurants. It’s like clockwork. The dabbawalas don’t make mistakes. But this charming little film imagines what might happen if they did – and if that mistake accidentally brought two lonely people together.
