The Durrells

When Louisa informs her children that she is to marry Sven they immediately want to vet him. Despite them all approving of the match, well all but Leslie, they feel that something is not quite right and Louisa can't help but agree. The speed in which Sven sets the date makes Louisa question the marriage further, but the family rally round and embark on the preparations – even Leslie who hides his severe looking scorpion sting. A shock discovery by Louisa leads to a dark night of the soul with Larry. Will the wedding still go ahead and will Margo manage to entice the highly reclusive Countess to the island's event of the year?

Eager to show off his growing menagerie, Gerry delights in setting up a zoo and is dismayed at the lack of visitors forcing Louisa to ask Spiro to drum up business. Leslie's scorpion sting makes Gerry question whether he should set his collection free but will he be able to give up his cherished collection?

Feeling overwhelmed by the Durrell's, Nancy suggests she and Larry get a place of their own. Larry is unsure, Louisa resorts to underhand tactics to discourage the move and surprisingly even Leslie makes a case for Larry to stay. When Nancy says she wants to return to the UK she gives Larry an ultimatum. Will he follow his love or stay with his beloved yet highly dysfunctional family in Corfu?
