Young William Kamkwamba lives with his family in rural Malawi, where he attends school regularly and shows great aptitude for his studies. Yet after land development and poor weather lead to a meager harvest, famine strikes the village, alarming the community and forcing William to drop out of school when his father (Chiwetel Ejiofor) can no longer afford the fees. Determined to find a way out of the life-threatening situation his family is facing, William sneaks into the school library to research—and soon conspires to build a windmill pump to irrigate the land. Caught between his father’s close-minded skepticism and the difficulty of creating a machine out of bicycle parts and scrap materials, William races against the clock to fight for his community’s survival. Based on a true story.
