Midsommar is a 2019 folk horror film written and directed by Ari Aster and starring Florence Pugh, Jack Reynor, William Jackson Harper, Vilhelm Blomgren, Ellora Torchia, Archie Madekwe, and Will Poulter. It follows a group of friends who travel to Sweden for a festival that occurs once every 90 years, only to find themselves in the clutches of a Scandinavian pagan cult.


Psychology student Dani Ardor is left severely traumatized after her sister kills herself and their parents by filling their home with carbon monoxide. The incident further strains Dani's relationship with her increasingly distant boyfriend, cultural anthropology student Christian. As summer approaches, she learns that Christian and fellow students Mark and Josh have been invited by their Swedish friend Pelle to attend a midsummer celebration at his ancestral commune, the Hårga, in rural Hälsingland. The celebration occurs only once every 90 years and Josh, who is writing his thesis on European midsummer festivities, regards it as a once-in-a-lifetime opportunity. Christian had not discussed the trip with Dani as he was intending to break up with her prior to the incident with her family. After an argument, he reluctantly invites her along.
