This movie is not for the faint hearted, but it's the most realistic one I have ever seen about the brutality of a military dictatorship. But what I like most is the description of the friendship of college students who, despite emprisonmente and tortures, keep their dignity and their desire to struggle jointly for a better world. A movie which should be watched by every apathic teenager - the shock may really make him/her mature his/her views and attitudes.
