On the night before graduation at Portage Northern High School, four friends Carmen, Vig, Ace, and Aanya walk through the quiet halls of their school one last time. When they stop outside their classroom, they decide to sit together and talk about their memories from the past four years, remembering the moments that made their high school life special. As they reflect, scenes from the lives of other seniors appear in montages, showing the many experiences shared by the Class of 2026. When they finally leave the classroom, Vig pauses and sees a group of younger students running in, ready to begin their own journey. In that moment, he realizes that while their time at the school is ending, a new chapter is just beginning for others.
