Forty-year-old Welsh mum Isobel Richardson can cope with most things: her husband's redundancy, a shortage of money, three spirited kids and a demanding old house. She sees the loss of Leo's job as a chance for new beginnings and her drive and determination propel the family towards a sparkling new life in Australia. Isobel's mother Helen, however, is devastated. Cold and unsupportive, she rejects Isobel's invitation to join in the family adventure and throws the guilt card firmly down on the table. When the family lands in Oz and the longed-for dream unfolds, unbearable guilt at leaving a broken Helen behind is compounded by the pain of missing absent son Ben – and all the while Mother Nature is hatching some plans of her own. Has the great Australian dream really eluded her after all?
