Roger and Giles are coming to the end of a late shift in Collumpton which has, so far, been rather on the quiet side. Before knocking off, they're asked to check out a vehicle heading their way on the Motorway – a vehicle which makes Giles very pleased to undertake the stop. A Porsche 911 Carrera 4 Convertible – or, as he puts it, one of the best cars ever made. It's got some insurance issues, hence their being asked to go get it.
