In a summer that seems straight out of a dream, a group of friends travels to a remote village in Sweden to attend an ancestral festival that occurs once every ninety years. Dani, a young woman dealing with a personal tragedy, joins her boyfriend Christian and his group of colleagues on this adventure, seeking a respite from her everyday problems. At first, the beauty of the surroundings and the hospitality of the villagers promise an unforgettable experience. However, as the days go by, the town's traditions reveal themselves to be increasingly disturbing and chilling.
As the group faces unusual rituals and an atmosphere rich in symbolism, the tension begins to rise. Dani, in particular, finds herself drawn to the warmth and community of the place, but the thin line between the fascinating and the unsettling quickly blurs. Those who were once friends become ensnared in a spiral of anguish and distrust. The relationship between Dani and Christian is tested, as he seems to disconnect from her pain and wrestles with his own insecurities.
As events unfold, the festival transforms into a surreal and terrifying experience, leaving Dani trapped in a web of emotional manipulation and shocking revelations. In a surprising climax, questions arise about love, loyalty, and loss, as fascination with the macabre turns into a struggle for survival.
