Global warming makes holes in the ozone layer, adversely affecting men’s sperm. Women who come into contact with it become “sperm zombies,” incessantly craving “more cock, more cum!”  Director Moore creates convincing scenes of zombie frenzy, yet there are plenty of laughs and some very hot (heavily oral) sex.

When a zombie girl mob invades a hilltop house with four girls trapped inside, the sheriff (Christian) comes to the rescue. Twenty or so topless zombies surround Caroline Pierce as she rides him in reverse cowgirl — the movie’s most outrageous scene. Eventually a “cure” is found — another good joke.
