Fremantle, an ageing academic and Kimberley a naive young girl from the reception desk at the University of Western Australia, who has barely reached the age of consent, arrive at Hotel Le Big Knob in Northern Tasmania, they have booked a deluxe room and plan to have a dirty weekend. Mauritius, a demonic headmistress from a top girls school in Melbourne, who is tired of being left on the shelf and Blake an apprentice chef with a preference for fun, arrive to take up the other deluxe room in the hotel for a bit of a slap and tickle. The problems begin when Fremantle and Mauritius suddenly come face to face and recognise each other, or do they? Add to the mix Eugene, a fantasising fat controller and Moira an ageing spinster with a passion for cleaning toilets and the result is an hilarious sexual romp but dicky hearts and bad backs rear their ugly heads. Can the weekend be saved?
