At the 'Windermere' guest house Sunny and Alvin Steele are preparing for another swingers' sexploitation weekend, though, unlike Sunny, Alvin is not really enthusiastic, and goes off to the garden centre to meet his bit on the side - and in doing so, he has a lucky escape as swinger Daddy introduces his Medusa machine. This creates an exercise in auto-erotic asphyxiation but unfortunately it goes wrong, killing all the swingers. All except TV personality Laurence Llewellyn-Bowen who has slipped out into the garden for a smoke and gets hit by the Legz Akimbo van driven by Geoff.
