Reeling after an unspeakable family tragedy, Dani (Florence Pugh) wanted to salvage her fraying relationship with her grad student boyfriend Christian (Jack Reynor). She opted to tag along with his classmates on a field trip to Sweden, where they’d observe the midsummer rituals at a throwback commune… but they’d only comprehend the cult’s true nature until it was far too late. Disturbing chiller from Ari Aster (“Hereditary”) co-stars William Jackson Harper, Will Poulter, Vilhelm Blomgren, Ellora Torchia.
