There are certain fantastic creatures in the City of Córdoba that only some can see. The Maquinist is one of them and summons everyone to get on the train that leaves the Córdoba Station for Retiro. His evil plan consists of turning these creatures into collectible dolls, by means of an alchemical dust that is breathed and everything that was real becomes fantasy, just as the fantastic becomes real. What is not in his plans is when the fantasy turns against him, and the limits of sanity are completely erased.
