Mexican wrestler Tinieblas purchases a painting of a deceased woman, disregarding warnings about it being haunted. Later, he's joined at his apartment by his partners El Fantasma Blanco and Mil Máscaras, along with two women, for a party. At midnight, the painting transports them all to colonial Mexico. To get back home, they must battle Spanish Conquistadors, Aztec warriors, and an evil witch whose mother – the woman in the painting, a relentless undead creature craving sacrifices – is the source of the trouble.
