In a recent three-month period the number of counterfeit cheques rose by 400 per cent, and detectives suspect one particular gang is behind this huge increase. In a series of dawn raids, police carry out arrests at 20 addresses in Leeds, Bradford, Huddersfield, Barnsley and Wakefield, and recover hundreds of stolen chequebooks and credit cards, as well as printing equipment and false identity documents. However, with no sign of the ringleader, a nationwide manhunt begins. Narrated by Richard Armitage
