Ageing swingers Donald and Jacqueline Stewart return to the hotel for another holiday and meet the new guests. There’s the Garvey family, whose teenage daughter Chantelle is hiding a secret, newly married Kat and Martin, gay couple Troy and Gavin, and middle-aged Geoffrey with his mother, who he likes to call his PA.Everyone comes together for dinner and an evening of “quality” entertainment at Neptune’s bar, but Chantelle brings the evening to a premature close when she collapses doing a Karaoke number and Janice finds out she is pregnant.

Martin and Kate set off for a trip into the town centre, but the outing ends in disaster when they keep taking wrong turns. Meanwhile, everyone seems to be worried about Chantelle's pregnancy - except Madge, who's convinced it's a deliberate attempt to ruin her holiday. Geoff tries to break a world record and Gavin and Troy are left open-mouthed at the evening's entertainment at Neptune's.

Geoff tries to break a world record and Gavin and Troy are left open-mouthed at the evening's entertainment at Neptune's.

Madge gives the wrong impression to Donald and Jacqueline, resulting in an awkward bedroom encounter. After an amazing night Martin feels like his marriage is back on track, but Kate can’t remember any of it. Troy gets rather drunk and starts flirting with Mateo. And at Neptune’s Janice becomes suspicious of a woman who Mick met earlier.

Mick forces his family to enter a pub quiz with a big cash prize, and is shocked to win the money. A furious Oracle demands a recount - and turns nasty when his request is refused. Madge fails to keep quiet after Kate tells her about Martin's infertility, and Donald tries to reassure Gavin about Troy.

The Garveys have a trip to the beach, where a cash-strapped Mick falls victim to a con, and later receives even worse news from a mystery photographer. Kate is scarred for life by an incident in the swimming pool and Martin tells her he thinks her fling with Mateo has livened up their relationship. And Geoff decides it's time he stopped going on holiday with his mum.
