Aubrey Plaza ('Emily the Criminal') stars alongside newcomer Maisy Stella in Megan Park’s ('The Fallout') Sundance hit.

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