I watched a part of this movie a number of years ago, but it was about an African American family that had a mentally handicapped fully grown daughter, her sister, and her mother. From what I remember, they were pretty much out of money to the point where the sister had to go out and ask people in the city for help. Then they find this hidden box with extra cash then when they run out, the daughter freaks out. I'm not sure if the movie also has butterfly symbolism or whatever, but I'm trying to find out the title aha. And no, it's not "Beloved".
