A woman's ghost appears to her husband to try and prevent his suicide and convince him to go on living. The longer she stays the less chance she has of entering heaven and the harder it is for him to move on.

Not being done as a short. I have fleshed out about 30 beats (use of a better term). Only three locations all of them I have unlimited access. I see her communication with her husband as "awake dreams".

He originally thinks suicide may reunite them. I think of her as the wife who cares for the alcoholic husband. She deep down knows nothing she does will help him. He can only help himself. Yet she can not stop.

How much is she willing to sacrifice? How long before he realises he is hurting her by letting her sacrifice everything?

I am in index card heaven at the moment.

Is this a short film?

If so the plot can afford less acts and a quicker resolution.

I would describe her as her self not a version there of instead of a woman's ghost a woman stuck in limbo.

It would be better to raise the stakes and give her a must achieve or else goal such as:
After dying in an accident a woman stuck in limbo must prevent her grieving husband from committing suicide in order to be allowed into heaven.

Hope this helps.

Perfect logline. For me anyway. It is not going to be my normal action/drama with people dropping like flies. I was talking to my daughter (filmmaker) and depending on how it goes. May consider shooting it in my house.
