The Ultimate Vampire Resource and Directory

Johnny Carter and Joan Hayden plan to elope but, first, visit a local lover's-lane for a compatibility check-up. Tooling along in the dark, with no headlights, they hit something, check it out and discover it is a little green man (in black-and-white) and scurry off to inform the local authorities. The police think it is a practical joke but, when they check it out, they find a man's body (white) there and charge the two with manslaughter. The victim actually had the misfortune to also run into some little green men, who came to earth via a flying saucer with bad intentions.
