Ethereal choral music accompanies a succession of images - the first, a social worker talking intently to a brittle, old-aged couple, whose terraced house is disintegrating around them. Cut to tower blocks, then to a football manager lashed by rain as he shouts from the touchline, then to a woman lecturing an audience in a room of Orwellian bleakness. This, one might think, is the opening shot in a campaign to raise awareness about the Samaritans or, perhaps, the Salvation Army.
