Hearts of Glass follows the tumultuous first 15 months of operation of Vertical Harvest (VH), a multi-story, state-of-the-art hydroponic greenhouse that grows crops while providing meaningful, competitively-paid jobs for people with disabilities. The film weaves the story of their launch with the personal journeys of several employees with intellectual and developmental disabilities (I/DD). Innovation and inclusion create a fertile environment for people and plants to grow. This documentary is an intimate portrait of social entrepreneurship at the intersection of disability rights and sustainable, local food production.
