Casey Beldon (Odette Yustman) is plagued by nightmare visions of strange looking dogs, and an evil child with bright blue eyes.
While baby-sitting Matty, her neighbor’s son attacks her with a mirror. After being hit with the mirror, Casey’s eyes begin to change color, an optician explains that she is experiencing Tetragametic chimerism and Heterochromia. After questioning her father she learns she had a twin brother who died in the womb. Casey begins to suspect that the spirit haunting her is the soul of her dead twin, being possessed by a dybbuk, wanting to be born so it can transfer to the world of the living.
Casey meets a woman named Sofi, who is revealed to be her grandmother. Sofi explains that she had a twin brother who was killed in Nazi experiments in Auschwitz when they were both just children (presumably having been experimented on by Josef Mengele, as Sofi describes him as looking like an angel and Mengele was often referred to as the Angel of Death). The boy was brought back to life by a dybbuk who intended to use his body as a portal into the world of the living. Sofi killed her twin to stop the dybbuk, and now it haunts her family for revenge. Sofi refers Casey to Rabbi Sendak (Gary Oldman), who can perform a Jewish exorcism to remove the dybbuk.
The exorcism is performed, but things go awry as the dybbuk tries to stop Rabbi Sendak from completing the ritual. Several people are wounded and others are killed. The exorcism is finally completed, and the dybbuk is drawn back from the human world. Casey’s boyfriend is severely wounded and later dies with Casey by his side. Casey mourns him and she soon finds out that she is pregnant by him, with twins.
