What happens when love runs out of time? For a 92-year-old mother, Mimi, who has cared 64 years for Dona, a daughter who has an intellectual disability, it means facing the inevitable—the likelihood that she will not outlive her daughter and the need to find her daughter a new home.

This poignant, heartbreaking and, at times, humorous documentary traces this process through the story of a 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% of whom live at home with family—and details the ripple effects of Dona's disability on three generations of a Texas family.
