The Seventh Letter (1989)

Some time ago Gerardo knew another man of the same age called Berardo. When he said the name, Berardo expressed his oppinion violently, saying that the «G» was owed him and that Gerardo, since he owned it had somehow stolen something from him. Berardo then tries to get something back which soon goes beyond a baptismal name. Gerardo whitnesses this strange spectacle of himself as a place where, after Berardo, other people try to get something back, something that escapes them about themselves. Three women - Adália, Miranda and Virgínia - are whitnesses to this game
