One mistake can change a life forever. Zoë lives a contented life in Fremantle. She works, she gardens and she loves her husband Archie and their three children. But the arrival of a new woman in her son Daniel's life unsettles her. In Sussex, Julia is feeling nostalgic as she nurses her friend through the last stages of cancer. Her husband Tom is trying to convince her to slow down. Tom means well, but Julia fears he is pushing her into old age before she is ready. She knows she is lucky to have him. She so nearly didn't ... These two women's lives are shaped by the choices they made back in 1968. In a time of politics and protest, consciousness raising and sexual liberation they were looking for their own happy endings. But back then Zoë and Julia couldn't begin to imagine how those decisions would send them along pathways from which there was no turning back.
