Through flashbacks, we learn that George, distraught from witnessing how his brother treated Annie, kills Simon by hitting him in the back with an axe. He brings Simons body back to the homestead, telling Annie that a tree branch had fallen on him. Annie, by this time, had been driven mad from the beatings and rapes Simon had forced upon her. She hits Simon posthumously on the head with a rock. She and George consummate their feelings. Days later, she admits herself to the gaol, while George has fled the homestead to stay with a neighboring family.Annie finds out while in the gaol that she is pregnant, but is not certain whether the father is Simon or George. She declares the baby girl as being Simons child, so that the child will always be welcome and cared for in later life. ........
