The documentary follows the steps of eminent journalist Edmundo Cruz of the investigation that he and other journalists conducted into the murder of the university professor and 9 students, arrested in 1992 during a military raid at the teacher training college of Enrique Guzmán y Valle, better known as "La Cantuta". The professor and students were never seen alive again. The remains of only five of the victims were ever found, among the barren hills on the road to Cieneguilla. The evidence led to the eventual conviction, in 2009, of members of the Grupo Colina death squad and of Former President Alberto Fujimori for human rights abuse crimes.
