From prisons to prisons documents the life of different ex-cons who are trying to reintegrate society. From the small recidivist thief, to the drug dealer, to the person who committed homicide, this documentary provides an opportunity for different ex-cons to speak about their precarious day-to-day, their uncertain future and troubled past. Straight forward, without artifice, complacency or voyeurism, the film reflects this fragile moment when the hope of a new beginning can turn to the best or the worst.
