I think your concept is good, the logline, as expressed by Danzig does need a little work

I would say a movie about a woman learning to use her physical abilities seems weird, Maybe she searches youtube, “How to use Physical abilities” then goes to the library and checks out a book on learning physical abilities. After that maybe she takes a class, finally after learning to use her abilities in the third act she saves the day.

Instead, I would focus on what she actually must do.

This is just an example yours would be different:
