New documentary special, taking viewers inside the world of law school Innocence Projects, where young students take on high-stakes cases of convicted murderers who claim they were wrongfully convicted.

Capturing the action in real time with exclusive, behind-the-scenes access at the University of Cincinnati and Texas Tech University, as the students visit prison inmates, track down key witnesses, and seek DNA testing that could prove their clients' innocence.

It is painstaking and sometimes dangerous work, but the students see it as the opportunity of a lifetime for them, and maybe the last chance for their clients.
