Mimi and dona (2014)

What happens when love runs out of time? For a 92-year-old mother, Mimi, who has cared 64 years for her daughter, Dona, who has an intellectual disability, it means facing the inevitable -- she will not outlive her daughter -- and finding her daughter a home. This poignant, heartbreaking and, at times, humorous documentary traces this process through the story of a wonderfully quirky and deeply connected mother-daughter duo. The film spotlights the challenges of aging caregivers of people with intellectual and developmental disabilities -- some 4.6 million Americans, 75 percent of whom live at home with family -- and details the ripple effects of Dona's disability on three generations of a Texas family.
