Baby Blood (titled The Evil Within in the United States) is a French horror film directed and co-written by Alain Robak, and starring Emmanuelle Escourrou and Jean-François Galotte. The film is about a woman named Yanka whose womb is invaded by a parasite that desires human blood. Yanka heeds the demand of blood for the creature until it requests to be carried to the sea where it was originally spawned.


A snake-like parasite crawls into the uterus of an abused woman and circus performer named Yanka. The parasite demands human blood from Yanka who is first reluctant, but then finds that the only relationship she has is with the parasite. Yanka commits murders to devour the victims' blood in order to nurture the parasite. The parasite tells her that it is a creature that will replace man as the dominant species on the planet in sixty billion years, and must be released in the ocean. The creature is eventually released in the sea where it abandons Yanka.
