When it rains it pours - monster machines. That attack during a funeral and ruin everyone's day. MI317 - the government department devoted to defending Britain from cosmic horrors - is under siege, so Arthur Wallace and his team must travel to Area 51, ably - and oddly - assisted by Agent Gran. But their travels don't end there, not when there's an Arctic town populated entirely by spore zombies and the 2.0 version of Clyde has some funny ideas about how to save the world.
