A furious Lexie discovers that Dorothy has taken over the island in the middle of the Loch for her latest business venture, a t'ai chi retreat. The island is a lucrative source of income for Glenbogle as it has the best fishing on the estate, and Lexie is convinced that Dorothy waited for Archie to leave before trying such a stunt. Together, Lexie and Golly concoct a plan to sabotage Dorothy's retreat and win back the island from under her nose. They successfully scare away Dorothy's visitors but, when the women cast off on the boats, Lexie and Golly find themselves marooned on the island with a disgruntled Dorothy. Meanwhile, Molly is trying hard to put her break-up with Andrew behind her. When a chance encounter with him at the local pub upsets her again, Molly decides to seek refuge at Dorothy's retreat to escape her fussing family. However, she's dismayed to find she's not alone on the island. In a desperate bid for freedom, Dorothy dashes for Molly's boat but, in her haste, only succeeds in scuttling the vessel. With night drawing in and their chances of being rescued diminishing by the hour, the castaways decide to put their heads together to find a way to escape off the island.
