The Unborn

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, she hears Matty's voice over the baby monitor. When she goes to check on the newborn, she finds Matty showing the infants reflection, then he attacks her with the mirror, and says "Jumby wants to be born now". The next day, Casey's friend Romy tells a superstition involving newborns and mirrors: they shoudn't see their reflections for at least a year. When she comes back from her run the next day, an ambulance is outside her neighbors house, and another neighbor tells her "the baby wasn't breathing", indicating what Romy said was true. After being hit with the mirror, Casey's eyes begin to change color, which an optician explains as 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 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 during World War II. 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. Rabbi Sendak doesn't believe her at first until he sees a dog with its head twisted upside down in his synagogue. During this time, the dybbuk kills Sofi and Romy, and Casey realizes it's getting stronger.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, Mark, gets possessed by the dybbuk and is severely wounded when Casey stabs him in the jugular vein to stop him from killing her and later dies with Casey by his side. Casey mourns him, and she soon finds out that she is pregnant by him, with twins.
