The quirky Kerrigan family lives together in a makeshift home they built themselves – with great pride and a bizarre attention to detail – a few yards from the edge of Melbourne, Australia's busy Tullamarine Airport. When a building inspector condemns the building and reveals that the government plans to use their land for an airport expansion, Darryl Kerrigan and his brood recruit hack attorney Dennis Denuto and prepare themselves for the fight of their lives.

Home is where the heart is in The Castle, a rousing Australian comedy that gives audiences an endearing family to root for.
