Bajo aguas tranquilas

A supernatural force is devouring the village of Marinbad and its inhabitants, and is threatening to spread beyond its geographical limits. A group of men from the village manage to convince the authorities to build a dam, which would flood the valley and therefore submerge the village forever, sealing the evil force under water. But something remained down in the depths when the waters covered Marinbad. Now, 40 years later, an array of disappearances and deaths in mysterious circumstances are threatening the village built next to the reservoir that now covers Marinbad. Something is still down there. Something evil. And on this anniversary, it's going to surface. (officiële tekst van distribiteur)
