The week before Christmas, 1929, Eoghan O'Keenan loses his factory job, and has to flee the slums of Chippendale with his seven-year-old sister Agnes.

On the north side of Sydney at Lavender Bay, Olivia Greene is working on her latest millinery creations and dreaming of becoming the next Coco Chanel.

A job on the Harbour Bridge for Eoghan, designing couture for the Governor’s wife for Olivia, and a chance meeting in the Botanic Gardens sees the beginning of an unconventional romance. From vastly different backgrounds, with absolutely nothing in common - from faith to wealth and class - it seems that the blue mile of harbour between Olivia and Eoghan will be the least of the obstacles ahead.

By mid-1932, as the construction of the Bridge is completed, the city is in chaos as the Great Depression begins to bite hard and the unemployed edge ever closer to a violent revolt.

And then Eoghan disappears.

Set against the spectacular backdrop of Sydney Harbour, The Blue Mile is a tale of the both wild and calculated risks a city took to build a wonder of the world, and of those taken by ordinary people to save a great love, against all of the odds.
