Teddy has a secret. She's so consumed with guilt that it compels her body to literally unravel unless she feeds off the emotions of others. Teddy’s parasitic condition is usually tempered easily and is invisible to most, unless she feeds from them. However, her insatiable hunger has already begun to threaten her safety. Trapped in her tiny Connecticut hometown thanks to a careless mistake which cost her a prestigious scholarship, Teddy grieves her father’s death and cares for her neurotic mother, Mercy, who is convinced scorpion venom is the only remedy for her own peculiar skin ailment linked to her daughter’s sadness. Once an aspiring songwriter, Teddy now merely alternates between shifts at the local market and visits to the house of her eccentric neighbor, Mr. Ridley, for fresh scorpions to bring to her mother. It’s during one of her routine visits to Mr. Ridley’s subterranean grotto of exotic animals that Teddy meets an unusual young girl named Kiiara. Immediately enamored with one another, Teddy soon discovers that Kiiara is hiding a gruesome secret, too – a secret that will threaten to undo everything Teddy has ever known and loved, and violently touch all those who cross their path with disaster.
