Following a trail of clues to a sleepy seaside village in the southwest corner of England, retired police detective, Albert Smith, aims to prove his theory of a master criminal by catching the ‘Gastrothief’s’ agents red-handed. With trusted former police dog, Rex Harrison at his side, the crime-busting duo know precisely who and what to look for. However, beneath the narrow streets of the picturesque resort a far more sinister plot is being hatched and if Albert were to look over his shoulder, he might notice a set of eyes lurking in his shadow. He is being hunted. To the backdrop of a cider and pasty festival, man and dog must risk it all save that which makes Britain great.
