This is a melodrama. I've never seen a woman duel. He must be giving her lessons. There's 3 people. The one with the sword is not in uniform. He must be the teacher and the others are the students. This could be outside maybe on a terrace. Why is there a china cabinet? The clothes are set in the Victorian Age. Look at his handle bar mustache! Why would a girl take up sword fighting? Maybe for self defense. Is she a Gibson Girl? They could be practicing for a play. The floor is tiled like mine in Florida.
This probably takes place in the Old Country of Poland or England. No, I think it's a scene for a play. It looks modern day because the man has khakis on. The others are wearing costumes. Dueling was old time 1800's. Their haircuts look modern. They could be rehearsing. It must be an opera. Look at the haircuts. One has no hair at all and the others have modern cuts. The bald one has khakis on. It's a rehearsal for a play. One has knickers on, one has khakis. Like people today...they're hanging. Steve Harvey on TV is impeccably dressed. Today they buy pants with holes in them.
Some are waiting for instruction for their part. They are watching the others rehearse. He's protecting himself from a student. Maybe he got nicked one time from a fellow student. She has a glove on to protect her hand. Swords can be flexible.
