Return of the odd-couple comedy starring Nick Helm, about the dysfunctional relationship between an uncle and his nephew, beginning one year on with 13-year-old Errol unable to pluck up the courage to ask Ben to drop the restraining order. Meanwhile, Sam is now a therapist and is struggling with a new client, and Andy is still stuck in a dead-end job, and has lost his enthusiasm for songwriting.
Andy tries to prove how mature he is to his latest love interest, while Errol wants to show a girl how cool he is, and Sam is desperate to impress Ben's girlfriend, Veronica. Unfortunately their efforts do not go well, forcing the trio to resort to deception in order to make a good impression.
Andy is wrecked with the flu, but when Errol alerts him to a lucrative song contest, it's off to the recording studio. When Andy suddenly refuses to collaborate, Errol endeavours to sabotage the recording. Now with Sam constantly asking for sex advice, the clock ticking and inspiration running low, Andy's going to need a genius idea and the help of a few surprising allies if he hopes to get the track recorded in time.
When Sam ropes Andy into chaperoning Errol's Halloween school dance, the family makes a joint oath to stay out of trouble. But that might prove difficult when Andy and Melodie get locked in a storeroom together by an old enemy who also wants to thwart Errol's plans to get his first kiss. Meanwhile, Sam's plans to behave look dubious when Bruce's ex Claire makes a surprise appearance. Things are going to get scary.
Andy is desperate for money to pay his rent, so he visits his dying estranged uncle in a bid to get in his will. Andy brings Errol along too, without Sam's permission, and together they take part in an unforgettable family reunion.
Suffering a string of bad news and on the verge of eviction, Andy receives a surprise cheque in the mail. Now all he needs to do is cash it and pay his landlord in the next three hours, while keeping Errol busy as Sam plans a surprise birthday party. But the universe might have other ideas.
