I couldn't turn up any reliable record for a title exactly called 'Women of a Free-Spirited Nature', so I went looking for films that match that vibe — and the one that jumped out to me first was 'Desert Hearts'. In that movie the central role is Vivian Bell, played by Helen Shaver, with Patricia Charbonneau as Cay Rivvers; the story really orbits those two women and their unexpected romance. If you’re asking who the lead is: Vivian (Helen Shaver) is the established, ‘lead’ character by profession and plot setup, though Patricia Charbonneau’s Cay is equally vital as the young, free-spirited force who upends Vivian’s life. The ending is quietly hopeful rather than tragic: after Vivian’s divorce is finalized she boards a train to return to New York, and Cay impulsively climbs aboard as it’s pulling away, agreeing to go with her at least as far as the next station — it’s a small, intimate moment that suggests they’re willing to try moving forward together. I like that ending; it’s low-key and believable, not melodramatic, and it feels true to the characters’ emotional growth.
