The Black Scorpion

An earthquake strikes Mexico, resulting in the overnight birth of a new volcano. Geologists Dr. Hank Scott and Dr. Arturo Ramos are dispatched to study this crisis at the village of San Lorenzo, the two men finding a destroyed house and a totaled police car en route. They find a dead policeman nearby, and an abandoned and seemingly orphaned infant. They take the infant to San Lorenzo and give it to friends of the child's missing parents, while being welcomed by the village's priest, Father Delgado. Delgado reveals that the property damage is caused by something that is slaughtering the livestock, the villagers believing the culprit to be a demon bull and have been pestering Delgado for divine assistance.
