Eva is just passing through Madrid. She spends her days there alone: she doesn't know anyone and isn’t particularly interested in getting to know new people. The city is therefore an unfamiliar place where she wanders aimlessly, her curiosity somewhat dampened. But one afternoon, at the Reina Sofía Museum, a man approaches her. His name is Dante and he is an Argentine historian researching labor struggles in his country and the career of Juan Bialet Massé.
