Yes, a concept as in… life in a nursing home and how that life is either jilted or improved upon by the people around it. Then I think, someone in the home unhappy with their life there that either finds a way to escape mentally or meets someone that improves their life in the home. Then I start narrowing down the story. Why is the person unhappy? What would make them happy? What do they ultimately want? What changes their life? How does it change them? Is this a good change or even more detrimental? Do they believe it is detrimental? and so on and so forth. Then you can think specifics and before you know it you’ve got a story with well-rounded characters, conflicts and motivations.
