Hippies from the seventies, Mac and Lottie made a ton of money in the days of their progressive soft-rock band Charisma. But they’ve got little left apart from the large, grand but somewhat dilapidated house where they raised their family. Mac and Lottie now decide, on a whim, to sell up. They plan to travel the world in style – as flash-packers, not back-packers – and blow the lot.

          However, their two elder children, now adults and far more sensible than their parents, see the house as their inheritance. Son Ilex fears they will come home to face a pension-deficient old age. Daughter Clover has plans of her own that involve a bijou second home in France, and the youngest, seventeen-year-old Sorrel, is looking forward to her gap year and would prefer to have a home to return to.
