Deep in a remote, snow-covered forest in Northern Europe, an isolated family lives together in a rustic wooden cabin. The eldest son, Alexi, works cutting trees despite suffering from severe epileptic seizures. Alexi shares a fiercely intense, boundary-pushing emotional and physical bond with his sister, Hege. Their blind mother, father, and younger brother live with them in quiet near-silence. The fragile dynamic of the family is disrupted when a young outsider, Johann, arrives in the forest to work alongside Alexi. Hege becomes drawn to Johann, triggering profound jealousy, emotional distress, and internal conflict within Alexi as he struggles to let go of his possessive attachment to his sister.
