It’s the year 1930, and Anna May Shahan’s world is about to change. The eccentric housewife from the small woop woop town of Esperance, Australia, lives on an isolated farm by the sea with her loyal husband James, and they lead a simple, hardworking life. That is until Anna’s beautiful widowed cousin Lottie returns from the States after being absent for over a decade. Lottie confesses to Anna her heart’s greatest desire to have a child, and Anna, in fear of losing her beloved cousin again, seeks to grant her wish by means of her own husband.

James knows his wife has some undiagnosed mental condition, blaming it for her salacious idea, and refuses to take part in it. But Anna is relentless, and finally one night successfully manipulates him into going along with her plan. She gets her way, but her choice to help her cousin soon brings devastating consequences for them all.
