La Casa del Terror plot
Casimiro, night watchman in a wax museum, feels even more sleepy than he would be because of his natural laziness. The reason is that his boss - the Professor - secretly drains blood from him when he takes a nap in order to conduct experiments with it to bring the dead back to life. So far no results have been made and the bodies have been waxed and put on display in the museum to cover up his crimes. His great chance, however, seems to come when he is informed that the mummified body of a "modern" man has been found in an Egyptian sarcophagus.
