Thriller movie about a young black woman who turns the tables on her captors/pursuers
I have seen this film a few times yet do not remember the title. It focuses on a young black woman driving on a country road in the woods, when her car breaks down two "good samaritan" white guys offer to help her when they encounter her. The woman escapes, is recaptured but ultimately takes the fight to them and is resourceful. In the end she learns the two tortured and murdered her sister, she kills the leader of the duo and saves another kidnapped woman who was a bartender I think. If anyone is familiar with this movie, tell me the title as I do not remember it and really liked this film.
