After a short time, Phil begins to suspect that there’s more to Des than what appears. We learn that Phil being assigned to Des’s cell is what Des had been hoping to effect all along. We also watch Phil show off his math skills when he learns that Des is planning a heist. In exchange for Phil’s silence, Des offers Phil 20% of the million pounds he expects to net from the heist. Phil exclaims, “That’s over thirty grand! Twenty percent of a million quid is over thirty grand!” Des’s response? “This isn’t going to work.” Once the nature of the heist comes out, we begin to see where Des’s fly on the wall character is a well-plotted, well-executed act; nobody notices him, and everybody spills their secrets around him, believing him incapable of doing anything with their secrets, or possibly even understanding them.

David Jason goes on throughout the series to portray a number of other characters, each as different as night from the day of his Des character, each seemingly better than the last. His mannerisms, speech, attitude, even the way he walks are completely in character for what the character he’s portraying at the moment would do. Each of the roles he seamlessly and naturally slips into, as if it were something he’s done all his life.

Stephen Wight expands and changes Phil’s character as well, and instead of the shallow, stupid, bumbling idiot we see at the beginning, he begins to show depth and abilities we hadn’t guessed at previously.

The execution of the heist demonstrates the brilliance of Des’s plan. It’s only after they’re nearly caught inside the house that Phil discovers the house belongs to none other than Benny, the prison boss, and it’s Benny’s diamonds from the heist he’s now serving time for that they’re stealing. Just when Phil thinks they can’t possibly be in straits any more dire, he learns that the pair are now going to break back into the prison! The perfect cover, Des casually explains.

The pair missed their planned method back into prison and have to improvise. Des says Plan B will be to get a ride in the trunk of the warden’s car. Phil balks, they argue, with Des trying to coax Phil into the trunk. Phil says, “Give me one good reason!” Des, visibly agitated, says, “Because I’m your father!” which stuns Phil.

The resolution to all of this concludes the first part, which is the pilot for the series. There are three more complete stories in the set, all three every bit as good and intricately, brilliantly written and acted as the first.
