It seems the start of a glorious summer as Alan Alton and his family settle into their new home in the Shropshire hills. Then the insects start to appear. First there's one... then hundreds... thousands... millions. A smothering tide of destruction covers the land.

Locusts.

As the heat-wave continues mercilessly week after week, the horde of invaders grows - a hideous, red-eyed devastation spreading across town and country.

Biting, stripping, devouring... and hating.

Before this onslaught the human population turns to flight. As panic grows, the death-toll also rises and the whole country is plunged into chaos. Britain is being eaten alive.
