A woman comes home to finds a wounded fugitive in her house. His partner has taken her daughter. The woman must help the man get medical attention and escape if she ever wants to see her daughter again.

Started plotting. So far, a house, a car and a 7/11. Won't need anymore locations. Any suggestions keep them coming.

World: major storm has taken out infrastructure, power, phone etc. this removes the "just call the cops" question. Single mum, 15 yo daughter, should be home but missing.

Good point. A ticking clock is needed. She doesn't try to break free because that would sign a death warrant for her daughter (perhaps). Her daughter is her focus.

She must achieve his goals to achieve her own.

I was thinking of moving it to a hospital, but I am trying to keep it in a single location, as long as the story doesn't suffer.

I think the premise can handle a single location.

I'm curious, do you want her to escape in the third act or do they both leave the house? I guess she must pull of an Houdini as the leading character in "Nick of time" does.
