Movie Plot idea

Plot:1

When a young girl dreams of pursuing ballet for the rest of her early years, she sets off to begin her training. She ends up falling in love with a much older man and they get engaged. One day, she gets her big break and is performing as the lead role when a very jealous suitor watches her from the shadows before he pulls out a gun and shoots her on stage during the show. Her fiance is sitting in front with a bouquet of roses and watches in horror as his fiance is murdered by the jealous man. He pulls out a gun to shoot the man only to have him disappear without a trace. The audience gasps, obviously realizing that was not part of the ballet and they rush to get an ambulance. They tell him that the ambulance won't get there in time, so he'd have to run to the closest one, which was only a block away. He grieves over his fiance as he rushes to a hospital, only to have her die before he can get there.2

He decides to get revenge on his dead love and starts going a little mad. He lives in an abandoned mansion that his fiance had wanted to buy and live in when they got married. He sits up his the attic, sharpening knives and typing on a type writer about some creepy nonsense that he also rambles on about when he tries to talk to somebody. Then he starts thinking he's seeing his fiance's ghost everywhere. He first finds her in the empty living room that used to be a ballroom, twirling around in her ballet shoes and calling out to him to come dance with her.3

He runs after her only to have her vanish, and leave him angry and upset again. One of the boys in town are compelled to bring up groceries to the man, as the crazy man never comes down, almost like he wants to starve. And whenever he'd come to drop them off, the man would start rambling about his fiance's ghost, spooking the boy even more. Until one day he decides to pretend to believe the man and see what he does. The man is surprised, but invites him in to talk with him.4

The boy sees the ghost and is scared, but then watches curiously as the man walks slowly over to his fiance, hoping she won't disappear. She stops twirling and takes his outstretched hands and the boy gasps, loud enough for the ghost to hear. She leans over and smiles at him before walking over and telling him to not be afraid. Her fiance is flabbergasted and insists that she tells him who killed her.5

She tells him his name and the man insists on getting revenge. She tells him not to, but a ray of sunlight flickers in through a crack in the ceiling and she disappears before she can repeat it. Her fiance gathers his things and finds out where the man is and heads out to find him, the still curious boy following secretly behind even when the man told him not to.6

The fiance arrives at the man's house and sneaks in and scares the man as he does not expect it. The fiancee shoots him in the leg, and the man staggers back and hobbles up the stairs quickly to grab a weapon, the fiance chasing behind.7

They fight with old swords the man has in his attic as they cut at each other. Then the ghost appears in the room and stabs the fiance in his arm and he drops his sword. He gasps in pain, and thinks it was the man. And right as the man towers over the fiance who is plopped on the floor after stumbling back and tripping, he raises the sword to stab him when he suddenly goes pale and falls over, a small knife in his back. As he falls over, he reveals the boy, his eyes closed as he winces, his arms in front of his face to protect himself. He sees the fiance and races off to get help.8

The ghost appears in the room and runs across over to meet her fiance and kneels by him. She looks fully human, unlike the other times when she was transparent. She looks at his arm and wraps a bandage around it, telling him that ghost weapons can't kill. He kisses her and they embrace.9
