DI Tim Yates and DS Juliet Armstrong are investigating the widespread theft of expensive farm machinery and keep on drawing a blank. They don't know whether they're looking for a gang, an individual or an organised network; nor can they find any trace of the machinery once it's been stolen. Meanwhile, local property developer and philanthropist Jack Fovargue is assaulted in the street, and seems reluctant to help find his assailant. Visiting one of Fovargue's building sites to persuade him to make a statement, DI Yates sees a quad that he thinks may have been stolen from a nearby farm a few days before. Fovargue denies all knowledge of the vehicle, while his foreman says he picked it up cheaply from a traveller. Tim obtains a warrant to search the site and discovers something far more sinister than another missing machine.
