Las huellas del mal

Argentina, 1892. Two mysterious federal police agents arrive in Quequén, a town on the Atlantic coast, to help solve a horrible crime. Two children have had their throats cut and their mother, alive although in a catatonic state, is the only witness. It will be Inspector Juan Vucetich, of Croatian origin, who will seek answers to the event through fingerprinting, an innovative procedure capable of identifying a person unequivocally using the unique relief of fingerprints.
