The twins Eliza and Ivy Bloom are the only surviving members of their family in the small town of Everdeen, after several mysterious deaths. Eliza is a professional woman who finds loose handcuffs and a knife in her home, confused about what is happening. Her eccentric twin sister Ivy is seen nearby, shaking a tub of pills. As Eliza leaves her house disturbed, the sound of pill shaking stops. She runs into her police detective colleague Mason but feels uneasy, like she is being watched. Ivy watches in the distance, pouring pills on the ground before leaving them behind.
