Francesca's friend Amanda is staying over. Fran warns Amanda of how strict her father is, but Amanda is a wild girl and just flouts all the house rules.

When Fran's off screen father discovers Amanda's poor behaviour, he instructs Fran to punish Amanda with pies and gunge. Fran is delighted, and carries out the punishment with gusto, and even gradually strips Amanda out of her dress, and bra and knickers, to leave poor Amanda naked and trashed.
