Elliot Tiber is an interior designer living in Greenwich Village, New York, who returns to his family's rundown motel in the Catskills during the summer of 1969. The motel is struggling financially, and Elliot's parents are in danger of foreclosure. When Elliot hears that the nearby town of Wallkill has canceled a planned music festival, he seizes the opportunity to bring it to his family's property, hoping it will attract much-needed business. He contacts the festival organizers, offers them a permit, and soon the event spirals into something much larger than anyone anticipated.

As preparations begin and crowds of young people arrive, the sleepy town of White Lake is transformed into an epicenter of countercultural energy. Despite logistical challenges, local skepticism, and resistance from his parents, Elliot finds himself at the heart of a historic cultural moment. He juggles responsibilities ranging from assisting the organizers to dealing with local authorities, navigating the complexities of hosting what would become one of the most iconic music festivals in history. Along the way, Elliot's experiences and interactions profoundly change his perspective on life and his understanding of himself.
