Segunda vez: a film essay around the figure of Oscar Masotta. A human crossroad, that was the very talented Oscar Masotta (Buenos Aires, 1930- Barcelona, 1979); a character that brings together literature, art, politics and psychoanalysis, in a fundamental moment in time, on the eve of the state terrorism in Argentina (1976). Masotta was a paradox: a Marxist disliked by the communist party; a literature and art critic forever struggling between engaged art and formal innovation, leading the Torcuato Di Tella introduction of conceptual art; and the pioneer of Lacanian psychoanalysis in the Spanish speaking world. The film consists of the reconstruction of some of the most representative happenings by Masotta, such as El Helicóptero, Para inducir al espíritu de la imagen, or El mensaje fantasma. A second important narrative element is Julio Cortázar’s short story Segunda vez (1977), introducing the notions of suspended time, disappearance, and terror. A third narrative element is brought on by the idea that “only a book can change reality” as in Museo de la novela de la Eterna (1967) by Macedonio Fernández. Dora Garcia
