An 18th birthday mushroom trip brings free-spirited Elliott face-to-face with her wisecracking 39-year-old self. 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.

A humorous cocktail with a twist of coming-of-age drama, My Old Ass doesn't throw out the wisdom with the reckless abandon of youth, and the effects are hallucinogenic.

Elevated by heartfelt performances from Maisy Stella and Aubrey Plaza, My Old Ass is a refreshing coming-of-age story that magically captures the contradicting essence of youth -- strong-willed, foolish and wise.
