Genre Research for film idea 1

My first film idea fits in with the genre 'Thriller' and is very similar to the film panic room. The film is about a divorced woman and her diabetic daughter take refuge in their newly-purchased house's safe room, when three men break-in, searching for a missing fortune. The womans daughter begins to struggle with her lack of treatment for her diabetes so the woman has to venture out of the panic room to retrieve the medical equipment. The trailer for the film is below.
