Britain is reeling from reports of a terrorist bomb on a film set that has killed a hundred people and, possibly, the brightest star in Hollywood, Thomas Bayne. Caught up in the middle of the national mourning is Susan Mantle - a rather hopeless tour-guide - who is seen crying on a park bench and is taken up by the media as a symbol of the blitz spirit. She is crying, though, for other reasons: she's just been told by a clairvoyant that she is about to die. Susan is swept into a media maelstrom, becoming the baffled and increasingly unwilling star of reality TV.
