With In Memoriam: O Roteiro Do Gravador, Sylvio Lanna takes his camera to the Rio de Janeiro film archive, the Cinemateca do MAM, in search of his in 1967 film O Roteiro do Gravador. We soon learn that while the film was deposited within the archive, it's exact location remains unknown today  – among the Cinemateca do MAM’s mass collection, some films can be difficult to track. Not having his film in hand, Lanna instead takes the opportunity to create an experimental love letter to this great archival institution, while exploring themes such as loss, memory, and rebirth.
