B&B proprietors Alvin and Sunny invite their weekend 'Sexplorers' to join them in a voyage of auto-erotic discovery - although Alvin would prefer to be at the garden centre. But who is the mysterious femme fatale in the dwarf conifers and what is the secret of the fearsome Medusa?

Back to Royston Vasey and The Windermere B&B, where swinger Sunny's latest private function ends in tragedy. Special guest Daddy arrives with his machine, Medusa, for an evening of sexploits.

While Sunny and her guests participate, her husband Alvin, who is tired of it all, escapes to the garden centre. There he finds much more than compost bins and potted plants... he finds love in the form of Miss Judith Buckle.

When he returns home, he realises something has gone horribly wrong and not even Juliet Bravo can save them.
