Doctor X

A monster lurks as New York newspaperman Lee Taylor investigates one of the "Moon Killer" murders, in which the victims are strangled, cannibalized and surgically incised under the light of the full moon. The trail leads to the cliffside mansion of Dr. Xavier, where the doctor and his colleagues conduct a strange experiment.

New York newspaper reporter Walter Barnett finds himself out of a job after he claims to have found actress Angela Merrova dead in her apartment - only the next day she showed up alive and threatened to sue the paper. Determined to investigate he discovers her involvement with a strange doctor who is an expert on human blood. Barnett then finds a connection to a series of gruesome murders where the victims were all found drained of blood.
