Sister Forever

When a school bus driving woman (Tyne Daly) has a heart attack, she makes one request of her three daughters (Ally Sheedy, Marla Sucharetza, Marceline Hugo) - she wants them to find their long lost brother, who was taken away by their father (Jack Davidson) 16 years ago. What they discover is that while they have struggled, their father has become a wealthy man and their brother is in school at Harvard.
