For ten years before Rubin "Hurricane" Carter's death, he and his friend and coauthor Ken Klonsky had been working to help free another wrongfully convicted man, David McCallum. McCallum was eventually exonerated and freed after serving twenty-nine years in prison. This is the story of how Carter and Klonsky, along with a group of committed friends and professionals, managed to secure McCallum's release. It details their many struggles, from founding an innocence project to take on the case, finding lawyers willing to work pro bono, and hiring a private detective to sift through old evidence and locate original witnesses, to the most difficult part: convincing members of a deeply flawed criminal justice system to reopen a case that would expose their own mistakes when all they wanted to do was ignore the conflicting evidence. A new district attorney willing to reexamine the case, a documentary film, and an op-ed piece in which Carter, on his deathbed, made a plea for McCallum's release finally turned the tide of justice.
