A father keeps his three adult children in a state of retarded development. They are deprived of books, education, television, indeed denied any access to the world beyond the electronic gates marking the perimeter edge of their known territory. In the place of knowledge is disinformation, disseminated on tapes. The sea is a leather chair, a zombie is a yellow flower, a vagina is a keyboard. And so on.

Ballet... well, what an irrelevance.
