The film, set in Mumbai, revolves around a mistaken delivery by the Dabbawalas (lunchbox service) of Mumbai, which leads to a relationship between Saajan, a lonely widower close to retirement, and Ila, an unhappy housewife, as they start exchanging notes through the daily lunchbox.

In this modern update of the Hansel and Gretel fairy tale (actually more like Gretel and Gretel), 15-year old Crystal is a bulimic delinquent who makes her living by beating and robbing potential "tricks". While awaiting a 25-year jail term, Crystal hooks up with a psychotic young lesbian named Cyclona, doing time for slaughtering her entire family. After escaping, they head for Mexico, where Cyclona's saviour Sister Gomez lives in a confectionery full of children. Along the way, they leave a trail of crack rocks, binging and purging, and dead people.

"Flexing" is a dance style forged in far east Brooklyn, at the dead-end of a handful of subway lines. Flex dancers channel the grittiness and crime of East New York into choreographed violence with gun movements, simulated bone-breaking, and the mimicked ripping of hearts from opponent's chests. Through battles dancers gain respect, craft an artistic identity, and sometimes find a sanctuary from the poverty and violence that saturates their neighborhood. No other style of street-dance is this violent, scary, or beautifully theatrical. In this purely do-it-yourself scene, creativity and ambition bring a community together around frequent dance-battle showcases that have begun to attract an international audience and may catapult the best dancers into careers in theater or film. Following a group of dancers for over two years, Flex is Kings explores the hopes and realities of this under-acknowledged and totally unfunded group of urban artists.
