We learned a lot from North Country (2005). The story hinges around the events leading up to and during a landmark court case involving sexual harassment - as a class action. The women working in the mines were severely harassed by the old boys' club of mine workers who did not want them there, and they fought back using the legal system. Did they win? Did the harassment stop? Watch the movie or listen to our review to find out!
