The opening shot is of a young couple (Gail Ganley and Ralph Reed) in a sports car necking. She excuses herself and the boy drives off. The girl is approached by a man carrying a silver briefcase. He removes his sunglasses and she screams and collapses on the lawn. The man removes a rubber hose and needle and attaches it to her neck and empties her blood into vials in his case. We get a close up his eyes and they are just milky white orbs. Title and credits run over pen and ink drawings.

        A Cadillac pulls up to a hospital, on the wrong side of the road, next to a fireplug, and in front of a no parking sign. Paul Johnson (Paul Birch) enters the hospital. He is greeted by Nurse Nadine Storey (Beverly Garland). He has come for a transfusion of blood. He refuses a blood test, which both the doctor and nurse find incomprehensible. Dr. F.W. Rochelle (William Roerick) comes out of his office and invites Mr. Johnson in. Dr. Rochelle explains no doctor on earth would do a transfusion without knowing the blood type of a patient. Johnson walks over to the lab bench, grabs a scalpel and cuts his wrist. There is no bleeding. Johnson explains to the doctor that it will bleed later. Johnson telepathically communicates with Rochelle. He agrees to the blood test, but swears the doctor to secrecy. Rochelle begins studying Johnson's blood as Nadine gives him his transfusion. Johnson asks Nadine to work for him. She agrees only if the doctor approves, which he does. Rochelle's orders are for a daily infusion of 500 cc of type "O" every night.
        A motorcycle police officer, Harry Sherbourne (Morgan Jones) is making his rounds when he sees Johnson's car. He prepares to write a ticket for multiple violations when Nadine and Johnson exit the hospital. Nadine and Harry know each other and she convinces him not to write up Mr. Johnson. She explains Johnson is very sick, so Harry agrees to escort Johnson home. At Johnson's residence, he is greeted at the door by his chauffer and butler, Jeremy Perrin (Jonathan Haze). Johnson tells Jeremy to prepare a room for the nurse. Johnson goes to the kitchen and removes several vials of blood and places them in the refrigerator. When finished, he goes down into the basement. Jeremy enters the kitchen, which he was expressly told not to do. He pulls out a clear cylinder and as he tries to open it, he is frozen by Johnson telepathically. Johnson tells Jeremy if he spies on him again he "will be eliminated."
        Nadine drives her car to the Johnson residence. She is carrying a single suitcase. Before she can ring the doorbell, Jeremy greets her. He makes a clumsy pass and she rebuffs him. He finds her attractive, she is disinterested. She enters the living room and apologizes for her late arrival. She explains to Johnson that she had to clean out her desk at the hospital. Johnson escorts Nadine to her room upstairs. He departs but l
