But the production company faced a real challenge; where to find a presenter who knows the criminal mind, who deals with offenders day in and day out . . . and, ideally, someone with presentationing skills.
Someone, in fact, like Rodney Stevens.
Rodney, who lives in Ibrox, is in a rare position in that he's worked as a criminal lawyer for the past eight years. But he was once an actor, and TV presenter - which makes for perfect casting.
"As a teenager I launched myself on a hopeful acting career," he recalls smiling in his Dumbarton Road office.
"And after a stint at drama college I found myself playing a series of lawyers in the likes of Taggart."
Rodney adds; grinning; "I was usually murdered early on. And stripped naked."
The young actor moved on to working on children's television.
"I would go off to Legoland and Deep Sea World and places like that," he said.
"And it was good fun. But it was at this time I began to become interested in the law.
"I was a member of Hillhead Community Council, and part of the protest group opposing building a pub in the park.
"So I was the one sent to the library, to study up on the legality of the proposal and I found the entire experience fascinating."
Rodney, having already had a grant to study drama, couldn't go back to university full -time so he did a part-time law degree at Strathclyde in the evenings.
Meantime, he worked in stage management at the SECC and the Mitchell theatre.
"Law was the hobby and acting was the day job which allowed me to pay for it," he said.
"Usually it's the other way around. But at the age 30 I was still in children's television, going on screen and saying 'Hi, kids.' And I thought 'I really can't be annoyed with this anymore.'"
Rodney, 38, finished his law degree and eight years ago landed a job as a trainee lawyer.
"It was tough to get a traineeship. I wanted to get into court and become a criminal lawyer. I didn't fancy working for a corporate firm.
"But I suppose having a colourful cv helped get me a few interviews. Having been an actor actually helped me stand out."
Rodney's work sees him represent a range of young offenders, from the sublimely stupid to the cunning apprentice gangsters.
It made him ideally placed to appear on a programme about Glasgow's underbelly.
"Just before I moved into my new offices on Dumbarton Road, I got a phone call from an acting friend who heard that the producers of The Scheme were making a programme featuring criminal lawyers.
"She had recommended me to the production team and I got a call. It all fell into place nicely.
"And, over three months, I've been working with the TV crew a day every two weeks."
The producers are trying to get inside the young criminal mind, to comprehend what drives them to jail.
"It's usually drugs or alcohol that gets them into trouble," says Rodney, the smile now fading. "There's lots of fighting, breaches of the peace, and knife crime, sadly.
"But what the producers want to understand is why do these offenders repeat, how do they get into the cycle of court and prison."
Rodney can offer some understanding.
"Recently I represented a shoplifter with a drug habit, and when I saw him in the cells and he said to me: 'Don't ask for bail. I just want to go up the road.' By 'up the road' he meant straight to Barlinnie.
"Jail, for him, was an escape from the drugs, the chaos of his lifestyle and 'to give his mum a break.'
It's sad prison is regarded as a respite home, isn't it?
"I don't know if that's exactly the case," he maintains. "Yet, while most don't want to go to jail, there are many offenders who seem to have no fear of the prison system. Or they feel it's a place where they can at least get some order into their lives."
Rodney deals mostly with 16-25 year-olds. But why would a client agree to be filmed?
"Some like the attention," he says, with a shrug.
Rodney Stevens may have once been an actor, but there's no denying his commitment to his second profession, or the effort he makes on behalf of his clients.
"I suppose the benefit of having clients over a period is you can't help give them a better service because you know them so well.
"It's a positive step that television is trying to understand where they're coming from. Perhaps it's a way to find answers."
The as yet unnamed series will be screened next year.
