Women dancing in a field but its not what it seems.

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.

A group of young people gathered on the countryside to celebrate midsummer dancing, drinking and romancing. And some fighting too. Followed by more violence, jealousy and guilt. On the journey home one of the cars the travel in collides with a bus.

Four nude girls prance about in a small clearing in a dense wood or green garden. Two stay coyly to the left, one dances in the front with a flowing, flimsy veil, and another, far right, mimics the dancer's movements.
