Elton never got over the death of his then four-year-old sister Ayla. Thirty years later he's still obsessed with her, even hallucinating her presence watching him as he has sex with his girlfriend Alex. He finds a pod in the woods that hatches into a grown version of Ayla. A grown version with the mind of a child, one that he will have to educate and teach how to be human. None of this sits well with Alex or his family, especially his mother Susan who has to deal with her daughter's bizarre return. Can this end anything but badly?
