The single series comprised six thirty-minute episodes starring Robin Driscoll, Rebecca Stevens, Pete McCarthy, and Tony Haase.
The arrival of an American suffering from amnesia coincides with a series of increasingly bizarre events including a rain of liver, people getting sucked into drains, migraines so severe that they cause heads to explode, and zombies taking over the supermarket.
The American has the key to the briefcase and he, Colin and Wendy open it and learn the truth of the situation: Middleford is a 21st-century rehabilitation prison located on a satellite orbiting Earth.
Unfortunately, his arrival has triggered a B-movie style doomsday scenario based on his book, The Night it Rained Liver, and the only way he can stop it and save Wendy from a grisly death is to sacrifice his own life.
The series has not been repeated since its original broadcast, nor released to home video or streaming services, possibly due to copyright issues arising from TVS's loss of its ITV franchise and subsequent sale.
