Death Begins At Conception

We all assume that we know how a zombie apocalypse will play out.  A mysterious virus or plot device will cause the dead to rise, who then roam the earth feasting on brains and spreading their affliction.  A logical enough forecast, but unfortunately dead wrong.  The year is 6 months after the film comes out, and a mysterious radioactive virus has been released from a laboratory in [insert hostile country of the day].  While harmless to adults and children, the virus potently infects fetuses, killing and reanimating them as deadly super-powered pint-sized zombies.  Why not just stop having babies until the virus passes, you ask?  Fair enough, but you’ve forgotten the first rule of horror movies- teenagers are front and center and horny as hell!  Pro-life becomes pro-death in this convoluted horror / political allegory.
