In a narrow pit, 11-year-old Suraj crawls through tunnels, scratching coal from rock in a northeastern Indian boom town. Such "ratholes" have become the sole source of income for many Nepalese migrants, whose lives intertwine in this chronicle of people living on the margins. With the loss of his mother, and an unreliable alcoholic father, Suraj is forced to become independent at a young age. Toiling in the dangerous mines with an indomitable spirit and stubborn smile, he hopes to one day beat the odds and return to school. A transporting and immersive journey fostering deep emotional connectedness to its subjects, this film illustrates how even seemingly insurmountable obstacles can help the human spirit grow.
