However, an evil creature that was inside the leopard bursts out of the animal's body, burrows into the wife's body and takes over her fetus. Yanka begins suffering from an overpowering appetite...for blood. Her unborn baby is craving for it. She kills again and again, until her little "Baby Blood" is ready to be born.
