Purificacion Crego is incarcerated since 11 years in the prison of Avila, at 100 km from Madrid. Today, she's 29 years old. She's two weeks away from leaving jail. La tercera vida is an encounter with this woman, in prison since she was 18, and who's about to get back to freedom. It's a closed door portrait, an intimate and spontaneous testimony during which the events of her past, her daily life in prison and her perspective on freedom are unveiled.
