“Trelew” tells the story of the escape of several "guerrilleros" imprisoned in a remote, high security jail in Argentina in 1972. Thirty years later, survivors relate how they planned and executed the high risk flight. Despite thorough planning however, only a few made it, the rest were captured and executed. Interviews with the prisoners, the victims and their families, as well as the wardens and executioners give a complex dimension to the story.
