This cheapo Mexican horror outing is set in Texas, filmed in Spanish, and centers upon a doctor who becomes a religious zealot after he dreams about the resurrection of the dead into the real world. He is certain that El Diablo is giving him a sign and that he will appear to bring them back on All Souls' Eve. To thwart Satan's plan, the demented doctor tries to gain custody of a certain corpse. Unbeknownst to him, six teenagers begin experimenting with a book of satanic spells and rituals in an old mansion set beside a cemetery. To enact their wicked mass, they head to the morgue and grab the corpse that the doctor wanted and then begin the ritual. Terror and tragedy follows when they succeed in not only reviving the corpse but every one else in the cemetery! To make matters worse, a group of children have wandered nearby, and the doctor must stop the blood thirsty zombies before it's too late.
