This is just a quick note to recommend the film Barbed Wire (1927), available from Grapevine Video.
Pola Negri plays a Frenchwoman whose family’s farm is commandeered by the authorities as a prison camp for captured Germans. At first she is prejudiced against them, because her brother has been reported killed in action. Gradually, though, she gets to respect Oskar, played by Clive Brook.
When a French soldier tries to rape her, Oskar comes to the rescue. He is arrested for attacking a Frenchman, but she speaks up for him at the trial, incurring the anger of the locals, especially the women. She is branded a collaborator.
