Donald Longtooth (Malcolm McDowell) is a vampire that works as the night watchman of his city's blood bank for escaping his true nature. After a while tho, the blood bank's owner Mr. Crosswhite says that the business is becoming dry and threatens his employees with layoffs for avoiding bankruptcy. So Donald is forced to return to his old ways attacking muggers and other dangerous criminals for having their blood, while dealing with the blood bank's secretary that is head-over-heels with him, vampire hunter Rupert Van Helsing (who looks a lot like Christopher Lloyd as Judge Doom) and the police detectives.
Like most of this season's episodes, this was one with many funny moments (the funniest of them with Mr. Crosswhite that is found by Rupert Van Helsing in Donald's grave and is stabbed in the chest) and I couldn't help but laugh from time to time. A must see if you are into the show and you want to see something different.
