It is rather long to start, but the tension rapidly increases for this short length thriler. Directed by Henry Cass, a brilliant grade B British director for whom BLOOD OF THE VAMPIRE is the most known movie. But he made other films, thrillers and dramas worth watching too. This one is tense, grabbing your attention after ten minutes, and the family taken as hostages is the main reason to concern many audiences. American film industry made dozens of movies of this kind; so this plot is not purely British, and I find it interesting. It looks like an Andrew Stone's feature. Good cast for a taut film.
