Watch Voix off (1989) Official Trailer

Two worlds are involved. The internal world, closed, virtually isolated, with just one tenuous, uncertain link with the other world - the telephone. The other, external world exists only to pass from one sealed-off place to another. Call each other? - you lose your voice before you get an answer: your head spins with non-existent voices. Telephone and answering machines are scheming devices. Just waiting in vain.
