Baby Blood (aka: The Evil Within) (DVD)

A pregnant woman is beaten and abused by her horrible husband, a circus owner. One day, the circus receives a live leopard from Africa, but the animal soon dies. Suddenly, an evil creature bursts out of the animal's body, burrows into the wife's body and takes over her fetus. Its bloodthirsty nature drives the woman into a murderous rage, and so she goes searching for victims for her new "baby" to feast on.
