Original Broadcast Feb 11, 2005
After four lawyers fail to get an innocent man out of prison, his friend takes on the case himself. He becomes a do-it-yourself investigator. He learns to read court records, he tracks down hard-to-find witnesses, he gets the real murderer to come forward with his story. In the end, he's able to accomplish all sorts of things the police and the professionals can't.
