Robert Bierman
After an encounter with a neck-biter, a publishing executive thinks that he's turning into a vampire.
A publishing executive is visited and bitten by a woman and starts exhibiting erratic behavior. He pushes his secretary to extremes as he tries to come to terms with his delusions. The woman continues to visit and as his madness deepens, it begins to look as if some of the events he's experiencing may be hallucinations.
