Joan hasn't decided to head off on an all-inclusive package holiday though, she's playing Crystal Henessy-Vass, Joyce's boss who arrives to inspect the resort.
Crystal's got high standards and Joyce is worried – particularly because they don't get on. Will we see cat fights of the like we've never seen in Benidorm before?
Elsewhere, Donald and Jacqueline have a surprise guest of their own, while Mateo and Lesley are left in charge of a group of VIPs. And the Dykes and Garveys come to blows when Tiger and Michael go head to head over a girl.
