The story of two men and a mysterious family, who repeat the same day forever in order to save the life of one of its daughters.

Argentina, 1915. Accompanied by a doctor and his beautiful daughter, Köhner, a ruthless foreman who rules a yerba mate plantation with an iron fist, arrives in the city of Posadas with the purpose of hiring workers.

In 1956, the humorous designer Oski made a work about the foundation of the city of Buenos Aires. Fernando Birri made a film from this work in 1959, using the original text of the German explorer Ulrich Schmidel. This film, which disappeared in the years of the dictatorship, was miraculously restored on video in 2000. The story that the documentary describes can be compared with the situation of Latin American cinema throughout all these years.
