Jess and Josh have a new rental house but no furniture, no job and no money. Josh's older brother Nick proposes a temporary solution - running Uncle Phil's cleaning business while he is overseas. Jess is initially horrified by the suggestion but when their power gets cut off it's clear they don't have the luxury of being picky.
In the aftermath of the morally challenging and exposing business venture as an erotic house cleaner, Josh begins to realise (with the help of his counsellor) that Jess will always push her own agenda. As a direct result he takes his brother Nick up on his offer to work in the family advertising business. Nick acts as a mentor, helping Josh get his life back on track financially, physically and emotionally. But his main focus is to remove Jess from Josh's life, forever.
When we last saw Jess (Jess Harris) and Josh (Josh Schmidt) they were about to embark on their big trip to the UK, but the real adventure starts in this new series of twentysomething, when they return home and discover that everyone has moved on. With nowhere to live, Jess and Josh temporarily bunk in with Nick (Simon Russell), Fiona (Jasna Harris-Currie) and their newborn daughter Chloe. But when Jess awakes in the middle of the night spooning Josh in a sexless marriage of convenience, all scored to the sound of a crying baby, she gets a glimpse of a life she never thought she would have. Rattled, they agree to take Nick up on his offer to move into one of his vacant investment properties, making him their landlord. In an attempt to discover where they may have taken a wrong turn, Jess and Josh find themselves looking for their life purpose in the last place anyone would expect - a uni open day. They take part in a career seminar designed for year twelve students and discover that Josh would excel in a creative environment while Jess is better suited to a trade. A slightly delayed surprise welcome home party is thrown for the pair, but the real surprise catches Jess off-guard when Billy (Hamish Blake) turns up with a new girlfriend by his side.
On a quest to find her hidden talent, Jess (Jess Harris) looks to her roots for guidance, and finds herself with a packed lunch and a hard hat ready to work for her dad (Glenn Robbins) as a building apprentice. Quickly becoming one of the boys, we soon discover where Jess's scamming skills come from as she learns from her dad how to do dodgy quotes and hold her own in pub brawls. Josh (Josh Schmidt) decides to turn his photography passion into a career, enrolling in a part-time course dedicated to building up an impressive photography folio. Between Josh starting school and Jess working on the site, the pair also has the shared task of finding a new roommate to help cover the rent. Jess and Josh interview candidates like they are casting for a reality TV show, both unanimously deciding on a musician with an unstable income and nothing but a guitar and his painfully good looks to contribute to the house.
