Mack & Rita

Determined to join her best friends on a Palm Springs bachelorette trip, Mack plans the getaway and asks her neighbor Jack to look after her dog Cheese. She is anxious about fitting in with peers and fears missing out on the fun. The trip is framed as her chance to reinvent herself, starting with the logistics of her care and travel.

On the first day, Mack encounters a strange pop-up tent promising to reveal her true self. Luca convinces her to lie inside what looks like an old tanning bed, and the transformation unfolds until she becomes a seventy-year-old woman. She freaks out when she sees herself in a mirror and realizes how drastically her life has changed.

Returning to the house after the transformation, Carla does not recognize Mack and tries to dismiss her from the trip. Mack must navigate Carla's disbelief and protect her secret in order to stay included. The moment heightens the tension about how the group will proceed.

Mack gains Carla's trust by sharing secrets that only they know, and confirms the backstory of her jewelry. Carla suggests Mack search for Luca and the tent to understand what happened. This revelation pushes Mack toward a plan to find the source of her new condition.

Mack leaves the others in a convertible and heads off to locate Luca and the tent. She promises she will still be at the bridal shower, even as the mission pulls her away. The hunt becomes a turning point as she takes control of her fate.

Back in the apartment, Mack runs into Jack and, in a moment of improvisation, assumes the identity of her Aunt Rita. Rita explains a plan to house-swap so Mack can work on a second book, letting her walk a mile in Rita's life. This deception sets up a new chapter where Rita's experiences begin to blur with Mack's.

Rita attends Carla's bridal shower and meets Carla's mother Sharon and the wine club crowd. They push her through activities meant to entice a younger, livelier version of herself, but the body stays resistant. The failed attempts to revert back deepen Rita's immersion in this new life.

Rita begins to embrace Rita's life, joining Pilates and other routines for social media posts. Jack invites her to a building rooftop outing, which deepens their connection. The wine club nights and public visibility propel Rita into a budding romance with Jack.

An Instagram event on the day of Carla's rehearsal dinner forces Rita to juggle two identities, but the pressure makes her run late and miss the rehearsal. Jack urges her to manage both sides of her life, yet the delay compounds the tension. The missed rehearsal becomes a turning point toward accepting the Rita life rather than returning to Mack.

Carla's circle pressures Mack, now living as Rita, to embrace the best years instead of clinging to an old self. Sharon and the wine club urge her to stop worrying about fitting in and to live boldly. The confrontation nudges her toward accepting her new life rather than seeking a return to before.

Mack tracks down Luca's tent and climbs into the broken tanning bed, emerging with a renewed sense of self that astonishes Luca. The moment seals her acceptance of the life she has chosen, even as the mechanism remains imperfect. She steps into the world with confidence and a new identity.

A year later, Mack is living with Jack and has written a second book. At a book reading, everyone who knew her as Rita attends, showing how completely her line between lives has blurred. The narrative closes with her continuing to navigate love, career, and self-discovery.
