I'm not entirely sure as I haven't delved deeply into it. But generally, it might be about the stories, experiences, and conversations of women, perhaps in a particular setting or community.
In the 'women talking original story', we can assume that there are women from different backgrounds. There could be a mother figure, who has the concerns of raising children and maintaining the family. There might be a single woman who is more independent and is fighting for her own place in the society. And there may be an elder woman who has seen a lot in her life and serves as a source of historical knowledge and guidance for the others. These are just speculations without more information about the story.
I don't think it is. It's likely a fictional creation with elements that might draw inspiration from real life but not be a direct account of true events.
Sorry, I don't know the basis of the story for 'Women Talking'. It could be adapted from a novel, a historical account, or something else entirely. You might try researching on entertainment news websites or film databases.
