Not much more is needed other than what is said in the title comment! This is a really good example of how creative imagination can re-invigorate what one might think is an almost dead sub-genre.
This was very much a small-scale family production - writing/acting/etc etc by husband and wife team - and written to be set in their own house although this was not actually used.
the use of sound was very imaginative and creative. - sometimes we were in the world of the silence of the lead female, other times not. It kept me on my toes and increased tension as I watched.
