A lawyer's letter delivers Mal and Jen another blow. They need to track down the park's mystery co-owner. And to do so, they'll need the residents' help.

Thanks to a mistake by Mal, Jen's over-critical mum Maureen arrives in Florida three weeks early - much to Jen's horror. She's totally not ready and the park is in a real state so, instead, she whisks Maureen, Tina and Rhoda off to Paul's park for a weekend of pampering. Meanwhile, Mal and Freddie hatch a new money-making scheme - and it involves hosting a highly unusual wedding.

Troy's wrestling nemesis Krakatoa rocks up at the park and demands a rematch to settle old scores. Good news for Mal - he sees a chance to get some much-needed, free publicity and starts cosying up to Krakatoa. This seriously ruffles Troy's feathers and before he knows it Mal finds the whole fight thrown into jeopardy.

The park's septic tank explodes and Mal and Jen are forced to turn to the only sewage expert around: Mayor Herman Bloch, the eccentric father of Tina's new boyfriend. Meanwhile, Freddie struggles to find his place at school, and Conan looks to take his and Tina's relationship to a whole new level... and it's not one Tina was expecting.

Having packed it all in for a life in the sun, things aren't quite going to plan for Mal, Jen and the kids. Mal's battling to keep the peace with burly park resident Troy and Tina and Freddie struggle to get to grips with life in an American high school. Meanwhile, Jen's in for an unexpected makeover when Rhonda invites her to a ladies' lunch.

The Pembertons pack up their home in not-so-sunny Yorkshire and head for Florida and the promise of beautiful weather at the Kissimmee Sunshine Park. What dad Mal discovers upon their arrival is ... not quite as he'd expected.
