A powerful story of cruelty that takes place in a type of privately run and religion based 'borstal'. These places existed in Germany in the 1960's where 'difficult' kids were sent and their placements were paid for by their middle-class parents - no crime necessary. The bullying, violence and lack of accountability became a national scandal. Superb acting by everyone.

Check out Wolfgang Petersen's 1977 film "The Consequence" (currently free at Amazon) which tells a very similar story of how parents could commit their "incorrigible" teens to these brutal institutional schools.

And if you make it to the end of "Sanctuary," you'll see that the German government has admitted these things were happening, and has paid restitution to some of the victims.
