Growing up is a trip. #MyOldAss, written and directed by Megan Park, is in select theaters September 13.

In this fresh coming-of-age story, an 18th birthday mushroom trip brings free-spirited Elliott (Maisy Stella) face-to-face with her wisecracking 39-year-old self (Aubrey Plaza). But when Elliott’s “old ass” starts handing out warnings about what her younger self should and shouldn’t do, Elliott realizes she has to rethink everything about family, love, and what’s becoming a transformative summer.
