1914, Australia: As war is declared, the idyllic world of Blue Water Station is torn apart when Oliver, the eldest grandson and heir, shares his desire to enlist in the army. His enthusiasm ignites his brother, cousins and friends to do the same, but upsets his sister, Tilly. After a tragic family incident, she is left to run the cattle station and take care of the older folk. A chance meeting with a sophisticated lieutenant opens up a friendship through letters, but it’s a rogue stockman who attracts her attention – with dire consequences… Surviving a baptism of battle fire in Gallipoli, Oliver is sent to the Western Front. But as the terrors of war impact him, he feels the heavy guilt of encouraging the others to follow him into combat. Will he, and they, ever make it home to Blue Water?
