Great bit of drama from Dorfman. I'd fail miserably at trying to explain the plot - the point is anti-censorship - but it's only 50 pages, so if you can find a copy in English, just read it.
P.S. The drama may be hard to come by, so try looking for the short story version in collections of Dorfman's works. I just ran across it in My House Is on Fire.
This was a great read and I feel that on stage it could be riveting. The play deals with political repression under both dictatorial and democratic governments and how both can overlap and how both are the flip side of the same coin. The way he achieves that on stage is also amazing.
