ninasimone2018 after reading available articles on this story and concluding the movie was pretty much following the same, it was hard to believe the sister becomes a detective at her own expense while the lazy incompetent new Zealand police does nothing even after she delivers them a case on a silver platter full of circumstantial evidence and witnesses. Finally after two yrs one detective wakes up and saves the face of the police and pushes the case forward. Recommended.
