Jess and Trish enjoy a vacation south of Acapulco on the Pacific Coast of Mexico.  Missing the bus to take them back to the hotel several kilometers away, the girls, along with their tour guide, seek shelter for the coming night.  

A fabulous day at a deserted beach turns into a nightmarish night as the two Americans ignore the pleas of their guide, ignore the warnings of historical village elders, ignore the danger as they enter... La Cuerva de los Muertos... The Cave of the Dead!!
