Haitian immigrant Josue Lajeunesse would put in 20-hour days as a janitor at Princeton University and as a cab driver in order to help fund his lifelong dream: modernizing the water supply system of his small native village, where residents have hours' journey on foot to the nearest spring. The global attention he received, and his post-2010-earthquake journey home to help realize his ambition, makes for a remarkable tale. Don Cheadle narrates. 71 min. Soundtrack: English.
