Luis Toñac (Carlos Arreaza), a renowned scientist and researcher, heads to a village with anthropologist Amelia (Ligia Petit) to investigate the appearance of dead animals without a drop of blood in their bodies. A creature called El Chupacabra is believed to be responsible for these strange deaths. The scientist downplays the possibility, considering it part of local mythology, similar to the legend of the death of a pre-Columbian princess who was reincarnated as his coworker.
