The Goodies's office accidentally gets completely covered in a solid block of concrete at Kew Gardens, ironically as part of an architectural design of careless loony Graeme.
The Main Works Department agree to save them, but only after completing a series of highways across Britain (drawn on the map as a game of noughts and crosses).
Gradually over a year later all the Goodies' utility services are discontinued, including the telephone (they cannot go out to pay the bills).
Tempers become short and Bill (arguing with Tim) says: "In this society, every single one of us is gonna clean the shoes."
Bill denies this, saying: "This isn't political discussion, we're just shouting at one another", to which Graeme replies: "Same thing."
The years pass, and the Goodies grow old, and they begin suffering from hallucinations, which is noticeable when Tim and Graeme are in conversation with each other, reliving their past.
