Mack (Elizabeth Lail) is tired of doing all the things she has to do to keep up with her friends and become successful in her 30’s. Her deepest wish is to be an older woman so she can just chill out and wear a good chunky sweater. But when she’s struck by lightning in a sound bath regression pod at Coachella and becomes Rita (Diane Keaton), a 65-year-old woman, Mack learns that the reality of being an older age isn’t quite what she imagined.
