Everyone seems to be leaving the Welsh village of Manod, and now Dylan Hughes is the only boy left in the village. As he worries whether he will ever find anyone to play football with again, his parents struggle to keep their petrol station afloat. So when the government takes over the old quarry in the mountain to store priceless paintings evacuated from a flooded London, everyone is pleased. The petrol station has customers and Dylan may even get the chance to have a kick-around. But then Dylan's dad leaves home and desperate measures are called for - which is how Dylan gets talked into committing 'The Perfect Crime'.
