Step Dave is a light-hearted, feel-good family drama which demonstrates one of the realities of modern life – that families come in all different shapes and sizes. In this series, home is where the heart is – even if that home is crammed full of kids, teenagers, ex-mother-in-laws and hangers-on. Dave, a 24-year-old ordinary kiwi slacker, finds his life turned upside down when he meets the girl of his dreams – Cara - and her three kids. Can this unconventional relationship survive the age difference and the pressures of the multi-generational household? Can Dave step up (no pun intended) and be a proper parent? Should he even try to? Can this unruly bunch live happily ever after as one big happy family?
