A look at the work of college students who take on the cases of jailed murderers who claim they're innocent. With exclusive, behind-the-scenes access to Innocence Projects at the University of Cincinnati and Texas Tech University, viewers watch as the students visit the inmates, track down key witnesses, and seek DNA testing that could prove their clients' innocence. We focus on the cases of Anthony Graves, a Texas death row prisoner, and Glen Tinney, a mentally ill Ohio inmate who pleaded guilty but now says he didn't do the crime. (thetvdb.com)
