Some Irish fella, who appears to be farming mud, accidentally digs up a mud-vampire (prob called Peat... Oh stop it!).
The mudpire attacks him a bit so he runs back to his house and falls asleep.
Whilst this is going on, there's also a young couple driving around locally, their car gets stuck, in more mud, then wander over to the farmer's house where they have to do battle with the now converted farmer and the source of the problem, Count Mudula.
Although I thought the sense of threat was a little absent, this is otherwise a solid little film and well worth a peek.
