When Sophie Butlin, a pioneering and successful young woman, flies from Sydney to Perth to attend the funeral of her Great Aunt, she is reunited with a distant relation from her childhood, Oliver Lannick, only to find him transformed from boyish geekiness to a confident and handsome man. Amidst the family turmoil she has been thrust into, Sophie seeks solace in Oliver's familiarity and easy-going personality, but soon finds her self caught in the throes of sinful desire and tormented by the century old problem of incestuous love. What exactly is Oliver's relation to her? Would she be committing the sin of incest if she succumbed to this intrinsic desire? As Sophie painfully questions her morality and seeks out the suspiciously ambiguous link between their families, decade old secrets are exposed and family resentments come to a violent conclusion.
