Louisa throws herself into running her boarding house, but mysterious guest Lazaros Vangelatos places the villa under police scrutiny.

Louisa finds herself fending off unexpected romanctic advances. Leslie's arranged hunt for new guest, Colonel Ribbindane, doesn't quite go to plan when his past revisits him.

Louisa meets Spiros' wife for the first time, and invites her to join the family on a trip to visit Larry in Kalami. However, the journey ends badly when their picnic is eaten by hungry animals, and Larry turns out to have left the island for Paris. As tensions rise, they seek the help of a local bar owner, who has a special gift for Gerry. Meanwhile, Margo brings a touch of the continent to Prue and Geoffrey's Dorset home.

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

The King of Greece is to visit Corfu and the Durrells are keen to be part of the welcoming committee. Meanwhile, things between Spiros and Louisa get cosy.

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.
