What is the main conflict in The Little School: Tales of Disappearance & Survival in Argentina by Alicia Partnoy?

The Little School is an autobiographical account of life in an Argentine prison for political dissidents. Alicia Partnoy, the author, was kidnapped and held in one of these prisons, known as the "Little School" for several months. During that time, the prisoners were constantly forced to wear blindfolds, prevented from talking to or knowing about one another, or any of the prison staff. Prisoners at the Little School were brutally tortured on a regular basis, constantly humiliated and degraded by the guards and supervisors, starved, insulted and mocked. All of the prisoners had been "disappeared", taken from their families without any explanation of their fates, and many of them were killed.
