This film is an historic document. Start to finish, a VERY slow build of tension, until the end... ends on a positive note, obviously you would figure this out from the title of the film, so, this really doesn't spoil the movie. Ok... so... by the fact it is a TRUE story I am inclined to say 5 Stars, however, I have one caveat which is basically the reality that too much foundational material ended up on the cutting room floor ( I assume)... we need to see it in the film, or at least in accompanying features. We need to know about these WHITE people who were imprisoned for trying to create justice in South Africa... it's just real information that isa missing... the who they were/are... how they were arrested, why, the GOOD work they had done... more of this... There is a scant very minimal portion in the film, just not enough to help audiences care about the fact that these who escaped were PARDONED LATER... begs the question, when does a regular person fight for truth and justice and risk prison...there are few heroes such as these... we need more.
