Sir David Jason (A Touch of Frost, Only Fools and Horses) plays Des, a wily and well connected master criminal. When we first meet Des in the pilot, he is in jail. He breaks out to do a daring robbery, then breaks back in to give himself the perfect alibi. The first series finds him on the outside, pulling a series of larger-than-life capers, with the help of an ever-revolving series of colleagues.
