The story of the tortuous struggle against the silence of the victims of the dictatorship imposed by General Franco after the victory of the rebel side in the Spanish Civil War (1936-1975). In a democratic country, but still ideologically divided, the survivors seek justice as they organize the so-called “Argentinian lawsuit” and denounce the legally sanctioned pact of oblivion that intends to hide the crimes they were subjects of.

The story involves a series of murders in Charron’s performing company, murders caused by various members getting doused with vitriolic acid. Turns out all the people killed have a common denominator in their past, one which has recently re-surfaced, and is out for their blood. Will the past be uncovered before it kills again? What awful secret has came back to haunt the living?

Renowned gunman Richard Martin is traveling on a train, held up by Billy Kane, a former student of Martin’s. Kane spares Martin, but only after shooting his hands. Years later, Martin meets an escaped convict, wrongly convicted for the train robbery. Martin trains his new student and both men seek out Billy Kane.
