Bob and Anna McAllister are a retired couple living a comfortable lifestyle in Australia. When Anna's breast cancer returns and Bob's heart condition deteriorates, they are worried about dealing with the end stage of life. Their adult children all have busy lives and they don't want to be a burden to them. They have enjoyed many cruises to the South Pacific and, after much discussion, they decide to take one last cruise - have one last hurrah - and not return. Their decision not only affects them but also has a great impact on their family. It is a love story about two people who cannot bear to be without each other and a family who are so busy rushing through life that they miss the signs that they are needed.
