El 90 (1928)
Through a succession of flashbacks, a grandfather tells his grandson about the outstanding episodes of the 1890 revolution, known as the "Revolution of the Park", against the government of Juárez Celman. Between the armed confrontations and the exaltation of the figure of Leandro N. Alem, the evocation includes a synthetic love story and culminates with the celebration of the second presidency of Hipólito Yrigoyen.
