The story is about the Kerrigan family, who have been living in their home—their "castle"—for years. Their house is next to the local airport. The airport wants the Kerrigans to move so that they can build a new building on the Kerrigans' land. Darryl Kerrigan is the father. He does not want to leave his house, so he fights the airport in court. At first he loses in court because his lawyer is not very good. Then he meets a very good lawyer (a Queen's Counsel). The Queen's Counsel argues very well and the Kerrigans can keep their house.
