The heart of Season 1 is the friction and eventual fusion of its two leads. Jane Fonda portrays Grace with a brittle elegance, masking her deep-seated insecurities with high-end fashion and a stern demeanor. Lily Tomlin’s Frankie is her perfect foil—messy, eccentric, and unapologetically emotional.

Grace’s daughters, Brianna (June Diane Raphael) and Mallory (Brooklyn Decker), represent two different paths of modern womanhood. Brianna is the sharp-tongued, career-driven successor to Grace’s empire, while Mallory is the seemingly perfect mother struggling with her own domestic frustrations.

The series begins with a dinner that changes everything. Grace Hanson (Jane Fonda), a retired cosmetics mogul with a penchant for martinis and rigid decorum, and Frankie Bergstein (Lily Tomlin), a bohemian art teacher who embraces herbal remedies and spiritualism, have never liked each other. Their only bond is their husbands, Robert (Martin Sheen) and Sol (Sam Waterston), who are successful divorce lawyers and long-term partners in their firm.
