During an unremarkable summer getaway, Mia and her friends Grete and Sarah experiment with a meditation app that blurs the lines between digital fantasy and reality. As the app’s features—like interactive dating and altered perception—deepen, their relationships shift, secrets emerge, and the world they thought they knew begins to unravel. When one of them ends up hospitalized and another disappears into the app’s darker functions, Mia must choose: save her friends—or embrace the infinite summer herself.
