Where can I watch Der Richter in Austria?

Dr. Joachim Glahn is the presiding judge at the Berlin district court and is known for his explicit sense of justice and truth. His daughter Luise is now embarking on the same career path and has just been admitted to law school. But then Luise then Luise is kidnapped and Glahn gets into an ethical-moral conflict: he should go beyond the limits of the law and set a murderer on the loose or he won't see his daughter alive again.
