After a family tragedy, a young American couple joins some friends at a midsummer festival in a remote Swedish village. What begins as a carefree summer holiday takes a sinister turn when the insular villagers invite their guests to partake in festivities that grow increasingly unnerving and viscerally disturbing. From the visionary mind of An Aster (Hereditary) comes this dread-soaked cinematic fairy tale where a world of darkness unfolds in broad daylight.
