Watch part two

Filmmaker: Rodrigo Vasquez

Coming to terms with a dark past is as difficult for societies as it is for individuals. In Argentina the darkness of the military dictatorship that ruled from 1976 to 1983 lies in the stories of "Los Desaparecidos", the "Disappeared".

For decades the kidnapping of opponents of the military junta who were then tortured before disappearing never to be seen again, has gone unacknowledged by successive governments.

But now these stories, and the experiences of those who survived, are finally coming to light. And for those who lived to tell the tale, talking of their experiences has been extraordinarily painful.

Enrique Sanchez was tortured for 12 months in a clandestine concentration camp. His torturers were the Paraguayan police, working alongside the Argentinian military as part of Operation Condor, a South American intelligence network.

But now, thirty years on, Enrique finally feels able to tell his story and he also travels to Argentina to trace the fate of a former friend and collegue.

The World and The Underworld is a powerful, personal, film made by Enrique's nephew Rodrigo Vasquez. It is a very moving film which lifts the veil on the reality of torture.
