For decades, the Brazilian military and a group of civilian researchers kept quiet about what they called Project Friendship: a string of alleged encounters in which flying disc-shaped craft supposedly made contact with air force personnel and local witnesses across Brazil starting in the 1950s. This film gathers surviving witnesses, researchers, and archival documents connected to the case, walking through the sightings, the photographs said to have been taken during the events, and the government's decision to investigate rather than dismiss the reports. Interviews trace how the claims spread from isolated witness accounts into a coordinated, if secretive, military inquiry, and archival footage and documents are used to support the timeline. The film treats the case as a genuine historical mystery rather than settled fact, laying out what witnesses reported and what officials did about it without resolving whether the contact was real. It functions as a record of one of Latin America's longest-running UFO investigations and the people who say they lived through it.
