When his new girlfriend April goes into labour, Stuart quickly finds himself having to rely on his ex-wife Kate to get her to hospital. As Stuart thinks he is getting a handle on the situation, he is forced to deal with a sexually promiscuous father, a daughter with a newly shaved head and the surprise return of his errant brother, who is on the run from some very unsavoury types. And that is before Stuart has to enlist the help of one tipsy neighbour to help with another neighbour, who he finds naked and the victim of a DIY circular saw accident.
