Summer 1982. While Germany and France are playing in the Football World Cup, the inhabitants of a small town in Provence are preparing to receive the German correspondents of their high school children. While Pierre Seguin, the mayor, meets the German teachers, his grandson Vincent meets Frank, his correspondent, who is blind. But Pierre's mind is elsewhere. His night was restless: he and his wife were woken up by what they took to be an intruder. There was no one there, but Pierre is convinced he saw a strange green phosphorescence. The young people seem to get along well, despite the language barrier. Until the moment when they in turn experience the supernatural.
