Lord Plaag from outer space has awoken from his slumber in a town near London, England called Hertford. Nigel is a comic salesman who must save his girlfriend from Lord Plaag's evil clutches (not the car variety).
A man is hanged 100s of years ago in Hertford; and comes back seeking immortality in present day Hertford on Halloween. He is assisted by a vampire. Only Jean-Pierre van Slam - Monster Killer can save the day?
