Newly separated couple Clyde (Jeffrey Dean Morgan) and Stephanie Brenek (Kyra Sedgwick) are at a yard sale with their two children, Emily "Em" (Natasha Calis) and Hannah (Madison Davenport), where Em becomes intrigued by a dybbuk's old box that has Hebrew inscriptions engraved on it. Clyde buys the box for Em. That night, Em hears whispering coming from it. She opens it and finds a tooth, a corpse of a moth, a wooden figurine, and a ring, which she begins to wear. Em becomes solitary and her behavior becomes increasingly sinister, to the point where she stabs her father in the hand with a fork. The house becomes infested with moths.
