I saw a preview for a movie where a blonde haired woman is abducted by several men and abused and held captive... She was wearing a white wife beater and white panties, tied up next to a wooden barrel of water, in a dusty, almost rustic looking environment... She ends up freeing herself and then seeks revenge on her kidnappers, fighting and killing them one by one... It's been within the last 2 years. It's not "I spit on your grave" and it's not "Savages"... Anyone have a clue?

Are you talking about Last House on the Left? Funny Games? Eden Lake?
