When a carefree wedding guest, Nyles, played by Andy Samberg, and a reluctant maid of honor, Sarah, portrayed by Cristin Milioti, have a chance encounter in the California desert, they find themselves inexplicably trapped in a time loop, forced to relive the same chaotic day over and over. Initially embracing the nihilistic freedom of their endless present, their dynamic shifts as they form a unique bond, exploring the surreal boundaries of their predicament. Their strange new reality is further complicated by the presence of another looper, a man named Roy, brought to life by J.K. Simmons, whose own motivations add a dangerous edge to their endless cycle. Directed by Max Barbakow, this inventive and witty film blends existential comedy with genuine heart, asking what matters when tomorrow never comes and every mistake can be undone. As Nyles and Sarah navigate infinite pool parties and wedding toasts, they must confront their pasts and decide what kind of future, if any, they want to build together within the confines of a single, repeating day.
