Three generations of Stewart women share a deep connection to their family farm in western Australia, but a secret from the past threatens to tear them apart. Widowed matriarch Maggie remembers a time when Italian prisoners of war came to work on their land, changing her heart and home forever. Single mum Toni has been tied to the place for as long as she can recall, although farming was never her dream. And Flick is as passionate about the farm as a young girl could be, despite limited opportunities for love. When a letter from 1946 is unearthed in an old cottage on the property, the Sunnyvale girls find themselves on a journey across the world to Italy. Their quest to solve a mystery leads to incredible discoveries about each other, and about themselves.
