Airs Sunday, October 2, at 6 p.m. Today, more than two million Americans are incarcerated. But every year about 700,000 prisoners return to society. About half of those released will be back behind bars within three years. One of the best, most cost-effective ways to reduce recidivism is to provide education to inmates. In this documentary, we follow a class of imprisoned students trying to make their way through their first semester, from orientation through final exams.
