Federal prosecutor Leo Ramírez is tasked with arresting Paul Schäfer, the leader of the German sect "Colonia Dignidad" in southern Chile, on charges of child abuse. Leo grew up in Colonia, but left when his brother died 20 years ago. It's the first time back from him.

In Santiago, Caro and her colleague Hannelore make some discoveries about the German businessman.

The buried cars are found to belong to missing dissidents of the Pinochet regime, tortured and killed at the colony. Caro informs Leo of the arms deals and asks him to look for additional shipments.
