Rule one: never ask a woman her age. But the Durrell children would never let manners get in the way of their curiosity, and it’s not long before Louisa (Keeley Hawes) is fretting that she’s over the hill.

Throw in the fact she’s missing Larry and is deeply hurt that Sven has a new girlfriend, and our stunning leading lady finds she’s not in much of a birthday mood.

Can her family – or perhaps her new love interest, Hugh (Catastrophe’s Daniel Lapaine) – cheer her up?

Meanwhile, Versilia has her sights set on Larry, but will he be stupid enough to fall for her charms?

Another sun-kissed hour of wonderful drama.
