Peter Loew, a sleazy NYC literary agent, prowls the bars in the evening looking for some action. One night he hooks up with Jennifer Beals, and in the course of their relations, she bites him on the neck. When he wakes up the next morning, Peter doesn't feel quite right.
He is irritable, and has a hard time dealing with life at the literary agency, where his secretary takes the brunt of his ire. Suddenly, it dawns on Peter that he was bitten by a vampire, so he goes out and buys a set of real fangs. Then the chaos begins.
