Mimi is 92, but it's her 64-year-old daughter who must leave their suburban Dallas home for an assisted living facility. Sophie Sartain's documentary "Mimi and Dona" airs on KERA TV at 10:30 p.m.
Sartain handles the fragile bond between mother and daughter with the tenderness of a family member - she is related to the pair. Find out more via PBS' Independent Lens.
