The Unborn is a supernatural thriller that draws upon the legend of a
dybbuk, a malevolent spirit that refuses to leave the human world and
inhabits the body of a person. Protagonist Casey Beldon (Odette Yustman)
is plagued by merciless dreams, visions of strange looking dogs, and an
evil child with bright blue eyes. After being hit with a mirror by her
neighbor's son, Casey's eyes begin to change color and 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. 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. The dybbuk
disappears after the exorcism and the death of Casey's boyfriend. Soon
afterward, Casey learns she is pregnant with twins...
