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.

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.
