Through The Looking Glass (released in France as Femme ou démon)[1] is a 1976 American adult horror film directed by Jonas Middleton and starring Catharine Burgess, Jamie Gillis and Laura Nicholson.

The film, which has avant-garde elements, concerns a bored socialite who finds herself drawn to a mirror that sexually arouses her.

She spends much of her time in the attic, masturbating in front of a gothic mirror that reminds her of her childhood and teenage years with her father.

The ghost performs manual sex on her and draws her into the mirror to witness several sexually charged scenarios.

These pique her interest and eventually culminate in a scene where Catherine witnesses her teenage self semi-reluctantly, then enthusiastically, take part in an incestuous encounter with her father.

She tries to deny his invitation to come into the mirror's realm as a permanent resident but the demon tells her that he knows that she will return as she always has in the past, as she is bored with the world and her husband.

This upsets Catherine, as she had previously forbid her daughter from entering the room and did not want to allow the demon access to Jennifer.
