A serial killer has been terrorising a community, killing "defective" women (in other words the disabled). In a house owned by the grumpy and ailing Mrs Warren (Ethel Barrymore) and Professor Warren (George Brent), the mute Helen (Dorothy McGuire) who works there, is now considered a potential next target.
Dr Parry (Kent Smith) wants to get Helen out of the house and get her treatment to recover her voice. Is the killer somewhere close at hand?
A superb and updated take on the dark house mystery, an atmospheric tale with excellent performances. The film is enhanced by little touches of humour and character. A very good film.
