Summary: Second World War "Careless Talk" short dealing with the dangers of conversations being recorded, made to be shown to RAF personnel
Description: With short light-hearted acted sequences the film briefly details the development of the gramophone. Beginning with the "earliest" gramophone - the Edison Phonograph with a wax cylinder recording of "If those lips could only speak" accompanied by a silent film style sequence with a man gesticulating to a "picture" of a girl in a gilded frame who then "thumbs her nose at him". Continuing with sequences of a later wax cylinder Edison Phonograph in a wooden case, a disc gramophone and then the "latest" super-radiogram with automatic record change. The commentary then warns "recording and reproduction has reached such perfection that German agents can record and transmit your speech with such rapidity that within a few hours any vital information you may have given away carelessly about service matters is faithfully reproduced in Germany" over a montage of shots of a telephone box, telephone wires and a note being passed from a man to a woman. The commentary continues with a warning "all you are likely to hear is the echo of your own voice in the form of a bomb... Keep silent for Victory!" The film concludes with an airman making the "V" sign to the camera "CARELESS TALK COSTS LIVES"
