A BBC drama, based on a group of students who investigate miscarriages of justice, begins on Thursday.
Lloyd Owen plays Dr Jon Ford
The Innocence Project, starring Lloyd Owen, is inspired by the work of real law students in the US and UK.
The first project - a legal clinic that usually looks at post-conviction DNA testing - was set up in the US in 1992.
There are now similar projects running at universities throughout the US, and attached to UK universities including Manchester, Leeds, Cardiff and Bristol.
'The West Wing'
The drama is described by the BBC as being about "failures in the process and cracks in the system."
Lloyd Owen, who plays Dr Jon Ford, said: "When I read the script, I thought that it was absolutely intelligent.
"I compare it, at its ambitious best, to The West Wing: that feeling that I am being a bit challenged when watching it."
Bristol University lecturer Dr Michael Naughton, told BBC Radio Bristol: "The project came out of research on how people can be wrongfully convicted and the limitations on overturning this."
His student Gabe Tan, who has worked on the project, said: "We choose cases in order of the sources available. It's based on the merits of the case."
And her peer Madeline Williams added: "We're mainly looking at murder cases. We review case material and we do our own investigations."
