In Western Australia, Sarah chuckles as she signs her final will and testament which will throw the metaphorical cat among the family pigeons. She dies a month later at the age of 94, laughing over a glass of wine with her ‘young’ neighbour Thomas, who is only 75, as they sit on the terrace of her luxurious waterside home built on a canal development in the city of Mandurah.

Sarah’s been married and widowed three times and has had a great life, been successful in business on her own account too. Her only regret is that she never had children, but you can’t have everything, can you? Now, she’s left her Australian house to two of her female descendants in the UK on condition they live in her Australian home together for a year. After that they can sell it and split the money between them. If either of them doesn’t last the full year, the next person on the list will be invited to try for the inheritance, but will still have to last a full year before the house can be sold.

Will these two women succeed? Will the experience do as Sarah had hoped and shake them out of their ruts? And when they find another surprise bequest from Sarah, what will they do with it?
