In Ecuador's remote Amazonian village of Jatun Molino, something is mysteriously attacking and killing people. Within one month, two adults and five children are dead. The two victims that make it to the hospital are found to have rabies. The analysis indicates that it is the type of rabies comes from vampire bats. Vampire bats are known to feed on livestock when jungle prey is scarce. Why would the shy nocturnal creatures suddenly be targeting human beings? An international team probes further into the tragedy that grips the Quichua community. A comparison to similar cases other South American countries provides possible reasons why vampires would be forced to turn their thirsty attention to people.
