Midsommar

Dani (Florence Pugh) and Christian (Jack Reynor) are a young American couple with a relationship on the brink of falling apart. But after a family tragedy keeps them together, a grieving Dani invites herself to join Christian and his friends on a trip to a once-in-a-lifetime midsummer festival in a remote Swedish village. What begins as a carefree summer holiday in a land of eternal sunlight takes a sinister turn when the insular villagers invite their guests to partake in festivities that render the pastoral paradise increasingly unnerving and viscerally disturbing.
Several friends travel to Sweden to study as anthropologists a summer festival that is held every ninety years in the remote hometown of one of them. What begins as a dream vacation in a place where the sun never sets, gradually turns into a dark nightmare as the mysterious inhabitants invite them to participate in their disturbing festive activities.
