This Land Is Mine (1943)

In a Nazi-occupied French town, meek and mild-mannered teacher Albert Lory lives with his mother. Few people, including his students, have any respect for him and he literally shakes in his boots during an air raid. He is quite friendly with his fellow teacher, Louise Martin and her brother Paul who also happen to be neighbors. If truth be told, Albert is quite in love with Louise but she is in a relationship with George Lambert and he feels she is quite beyond his reach. Paul is a member of the resistance and is killed when Lambert informs the Nazis. Outraged at what he's done, Albert arrives at Lambert's office just as the informer commits suicide. Albert is charged with murder but the local Nazi commander, Major Erich von Keller, offers him a deal: if Albert agrees to remain silent rather then continue a speech in his own defense which is arousing fellow citizens, he will ensure a not guilty verdict. Albert returns to the courtroom and in an act of bravery urges his fellow citizens to fight their oppressors.
