A senile old man is attacked in what appears to be an open-and-shut case of burglary. But Mike suspects the old man's obsession with his deceased son may have pushed his loved ones over the edge. Meanwhile, Greengrass organises the annual Aidensfield car rally and subsequently turns the rulebook upside down by agreeing to help one of the racers cheat.
