Six years after an apocalyptic event, Sarah lives alone in a farmhouse, her time spent cleaning, piano playing and writing in a diary.
Ryan shows Sarah a sketch he had made of her, years ago as she and her father were in a city, and has searched to find her.
As Lili attempts to have her sister force Ryan away, Sarah becomes attracted to him and eventually begin a romantic event in the grasses outside the house.
He bandages her wounds and attempts to undress her in the bathroom, but denies his assistance much like how her sister refused help a few days ago.
Along the walk she confronts Ryan, who pushes a finger into her abdominal wound, he tells her it hasn't been six years since anything and that was all in her head.
Lying on the ground she recalls walking along a city street with her dad as he presents her with the very same lucky charm necklace.
Closing credits are featured over Mimi Page's "Jigsaw", performed by the film's actresses Charity Farrell and Lili Reinhart.
