Idea for a film
When a poor old lady discovers she has mice in her apartment, instead of hiring exterminators, which she couldn't afford anyway, she shares what little she has with them, including, unwittingly, some of the experimental drug she is on for her memory loss. This boosts the mice's intelligence and they come to understand that she is making a sacrifice for them, the smallest of creatures. They start to use their new found smarts to help her, without her knowing it. She assumes its the super of her building but when she thanks him effusively, he assumes he has lost her marbles and starts organising for her to be put into care so he can get possession of her flat. The mice have to form a plan to save her and, in doing so, reveal themselves to her. It ends with the super thwarted, the little old lady still in her apartment and the mice looking after her.
