1920. Having disobeyed the wishes of her aristocratic family, Lulu Pearson, a young and talented Tasmanian sculptress, finds herself alone in London in the wake of the Great War. The future is looking bright until, on the eve of her first exhibition, Lulu learns she has inherited a racing colt called Ocean Child from a mysterious benefactor, and she must return to her homeland to claim him.
Baffled by the news, Lulu boards a ship to Tasmania to uncover the truth behind the strange bequest, but it seems a welcome return is more than she can hope for. Unbeknownst to Lulu, more than a few fortunes ride on Ocean Child's success - it seems everyone from her estranged mother to the stable hands has a part to play, and an interest in keeping the family secrets buried.
