Hammer House of Horror The Silent Scream

A criminal soon to be released was previously not only visited by his wife in prison, but a seemingly "good-doer" to assist him with some "work" on the outside... it's in a petshop, surely innocently looking after pets, hasn't ANY agenda??? Peter Cushing, Brian Cox and Elaine Donnelly star. This is an epsiode from the classic British TV anthology series, produced by the original "Hammer" studios of British horror fame.
