Seventy Is the New Thirty

Thirty-year-old Mackenzie Martin works as an influencer in Los Angeles, although she likes to consider herself a writer. Her first and only book is a series of essays on being raised by her now deceased Grammie Martin, the coolest old lady in the world who allowed her to be herself, whoever that may have been. As such, Mack has always felt like an old lady, just like her Grammie Martin, stuck in a young person's body. She has put on an outward appearance of youth to attempt to be accepted, her best friend Carla the only person, besides Grammie, to who she has ever felt she could truly be herself. So on Carla's bachelorette party weekend in Palm Springs, given permission by Carla to forgo a typical young person's bachelorette party event, Mack instead finds a pop-up "blessed and regress" tent where she feels the need to vent about her conflicted life. Coming out of that situation in the tent, she discovers that she has indeed turned into a seventy-year-old woman as per her rant. The only person to who she, in her seventy-year-old body, feels she can confide is Carla, who in turn thinks the only way for Mack to regain her true thirty-year-old body is to locate that same blessed and regress tent wherever it may next pop up. In the meantime, they pass off her seventy-year-old self as Mack's Aunt Rita, the two who have done an indefinite house swap. As Rita, Mack has to learn how to love her new body and life for however long this will last, which she is able to do with the help of Carla's mother, Sharon, and her group of similarly aged friends, and Mack's forty-year-old neighbor, Jack, a man assured of himself and what he likes, in this case being seventy-year-old Rita.
