MADRID, 1982.
Comandante Leopoldo Guzman has decided it is time to disappear. Franco is dead and there's no place in the new order for the former head of the tyrant's secret police. But first, Guzman needs money. Luckily, blackmail has always come easily to him - after all, he knows where the bodies are.

And so he should. He buried them.

MADRID, 2010.
Fifteen tangled corpses in a disused mine, three bound skeletons in a sealed cellar - a trail of dead that has led forensic investigator Ana Maria Galindez to one Comandante Leopoldo Guzman.

Guzman himself disappeared decades ago but she fears his toxic legacy lives on. Her investigation has revealed a dark conspiracy born amid the corruption of Franco's dictatorship, a conspiracy that after decades in the shadows is finally ready to bloom.
