Young adults Tarquin, Jonah and Leonara are recent escapees from The Royal Jericho Hospital.

Already challenged by severe physical and mental disabilities, at Jericho they were treated as little more than laboratory rats by evil Governor Bernard and his depraved Chief Physician, Dr. David.

In this episode, the hospital crew arrive at Tarquin's mansion to re-capture our heroes. Bernard convinces Tarquin's Aunt Edith that no-one will be harmed, but can he be trusted?
