I can GUARANTEE YOU have never seen this movie. Probably never heard of it. Came out in 2015. This is an upper level SOLID FILM.
Charlize Theron stars as the lone survivor of the mass murder of her family when she is a child. As America is obsessed with crime this case got tons of notoriety and she was famous for some time. Once the book deals ran out and go fund mes 30 years later she broke and behind rent. Oh and the person they convicted of killing her family was her older brother. So, that complicates things.
She gets approached by these true crime fanatics who after all these years believe that the brother is very innocent. And at first reluctant she agrees to work with them to find out, out of need of money.
The story than follows this group as SHE works on accepting that it might not have been her brother (even though she lied to the police at a young age and said it was) as the only eye witness, and the group putting pieces together that could completely clear his name. It is a fun movie with a lot of turns and solid story telling. Worth one watch for sure. That is a review.
