Gavin has a new holiday companion; The Garveys can't find Madge, but do find Cilla Black; Mateo is introduced to his new colleague Les (aka Lesley); whilst Les's son Liam tries to spend time with girls Natalie and Sam.

Noreen checks in at The Solana with her irritable daughter Pauline. Meanwhile, to take their mind off of Madge's financial woes, the Garveys decide to head to a water park, and when Noreen and Pauline show up, events take a bit of an unexpected turn. Mateo tries to get Leslie fired.

The Garvey's get a bit of a shock when they discover that Mel's debt has been taken on by some gangsters. They find themselves attempting a very risky bet to pay off what they owe. Noreen's problems with Pauline continue as she's decided she wants to leave Benidorm early. Meanwhile, Liam is still stuck to Natalie's side, much to the annoyance of Sam.

Benidorm is under siege from a freak storm and Les/Lesley attempts to arrange a bingo game with rather unusual prizes. Pauline learns that her flight has been cancelled and comes to the conclusion that a drink might help. After a good looking stranger from Janice's past shows up in Solana, she fails to notice that Michael is having a holiday romance. Natalie continues to have man trouble and Donald has bad news.

Pauline continues to drink permanently and everyone is looking forward to Eighties Night with guests Bananarama. Madge discovers that the lease on a bar could be coming and she has to decide whether she could live in Spain on her own. Kenneth takes Gavin out in an effort to try and cheer him up. Liam continues to attempt to win Natalie's heart but she is after Mateo. Mateo is talked by Leslie into going on a double date but nothing goes to plan. Bananarama end up finding an unexpected third member performing with them on stage.

Les/Lesley discovers some of Donald's clothes on the nudist beach - and it seems that Donald has left Jacqueline a note. The Garveys are gearing up for the opening of Madge's new bar, but when Lucky Kev arrives with some free tickets for a theme park, Mick packs the women and children off for the day. Pauline turns to the bottle as she awaits news on her divorce. Jacqueline, Kenneth and Gavin head off to pay their respects to Donald - but nothing goes to plan and Jacqueline is involved in a rather unusual water-skiing accident. As Gavin's patience with Kenneth reaches its limit, Troy appears - and brings some life-changing news.
