Josh and Cornelia, a childless married couple in their mid-forties, are feeling stuck in their routine and creatively stagnant. Josh is a documentary filmmaker who has been struggling with his latest project for years, while Cornelia produces documentaries alongside her father, a celebrated filmmaker. Their complacency is upended when they meet Jamie and Darby, a free-spirited, energetic young couple in their mid-twenties. Enamored by the youthful enthusiasm and unorthodox lifestyle of Jamie and Darby, Josh and Cornelia find themselves invigorated, plunging into activities they had long abandoned. They attend hip-hop dance classes, try on new fashion trends, and even take part in drug-fueled adventures.

As Josh grows closer to Jamie, he finds inspiration to rework his stalled documentary project. However, this revitalization also brings an unsettling realization as he starts to notice discrepancies in Jamie's motives and ethical approach to filmmaking. While navigating this new friendship, Josh and Cornelia must confront the growing divide between their past ideals and present realities. In their attempt to reclaim their youth, they begin to question what authenticity truly means to them, leading to tensions and self-reflection that challenge the foundations of their marriage and careers.
