Whats the name of this movie(Argentinian)?

I remember watching a movie earlier this year about the military coup in Argentina. It was about a student who was taken by the anti-communist junta and put in a small detention camp in a villa somewhere in the countryside together with other people being accused of being communists. I have tried to google it but since I dont remember a lot of details this has proven hard to find. Any ideas?

Reservoir Angel

It rings a bell to me...was it based on a book? Cause I remember reading a book that sounds similar to that, but can't remember the name.

It's not Missing is it?

Missing takes place in Chile...so I assume not.
