More than 30 years after committing one of Argentina’s most infamous family murders, the story of Ricardo Barreda is landing on streaming platform Prime Video.

“Barreda,” a new Argentine film directed by Daniela Goggi, will premiere exclusively on Prime Video on August 28, bringing the gruesome murders to audiences in more than 240 countries and territories.

Ricardo Barreda was a dentist from La Plata, a city about 60 kilometers south of Buenos Aires. On November 15, 1992, when he was 56, he killed four women with a rifle at the family home: his wife, Gladys McDonald; his mother-in-law, Elena Arreche; and his two adult daughters, Adriana and Cecilia.

The killings became one of the most shocking criminal cases in Argentina’s recent history.

What made the case particularly controversial was not only the brutality of the murders, but also Barreda’s attempts to explain what he had done. He initially tried to make the killings look like a robbery and later presented himself as a victim of alleged mistreatment by the women.
