Louisa tries to raise some money by selling homemade food, which attracts the attention of another Englishman. However, a former lover threatens the family's idyllic existence. Gerry comes up with a plan to breed otters, Leslie accidentally shoots Roger, and Margo considers becoming a nun.

Larry's latest novel is being published in England - but his siblings do not seem to be very impressed, his mother is more concerned with baking food to sell at the market, and even his attempts to show off in a local bar go unnoticed. Louisa attempts to make it up to him by organising a public reading. Leslie overhears Pavlos explaining to Margo how he makes liquor out of kumquats, and decides to launch a business venture brewing his own - but his sister does not approve of stealing the monk's recipe.

Celebrating her birthday motivates Louisa to adopt a more youthful look. Gerry has a bewildering time with Kralefsky.

With the house guests getting ever more rowdy, Louisa worries about the villa's reputation. Margo finds a surprising way to bond with Maud, while Gerry realises he has feelings for Galini.

The residents of Corfu are excited at the prospect of an imminent official visit from the King of Greece, and the Durrells are keen to get themselves involved with the welcoming committee. Leslie takes over leadership of a scout troop. Love may also be in the air for Margo as she makes her return home to the island.

With storm clouds gathering, the islanders realise they can no longer ignore the rumblings of war, just as it looks as though the Durrells - particularly Louisa and Spiros - may have found their happy ending. Larry marks his return by throwing an audacious play for the locals, but there are surprises for every member of the family. Series finale.
