Camillo died in 1968. Almost fifty years later, Marco gathers his whole family for a lunch. With his family he wonders about Camillo, his twin who disappeared when he was only 29 years old.
Brothers. The grandchildren. The sister of the girlfriend of the time. A psychiatrist. A priest. Speaking with each of them, recalling those years and those facts, Marco reconstructs the pieces of the past, finally giving body to a ghost he has dealt with throughout his life.
Marco Bellocchio, through his family, revives the story of his brother, without filters or modesty, almost an investigation, which reconstructs a historical era and weaves the red thread of so much of his cinema.
