Baby Blood is a 1990 French body horror film directed and co-written by Alain Robak, and starring Emmanuelle Escourrou and Jean-François Galotte.

Its plot follows a former circus performer who is driven to commit murders and consume blood by an ancient parasite that has invaded her womb.

In the United States, Dimension Films acquired home media distribution rights, releasing it directly-to-video in 1994 under the alternate title The Evil Within.

In June 1991 in northern France, a tiger arrives by cargo ship from Africa, where it is acquired by a local circus overseen by the abusive Lohman.

Before the circus can begin training the tiger, it is found dead in its cage one night, its body inexplicably burst open.

Some time later, Yanka arrives in Paris and begins working as a waitress, where she catches the eye of Richard, a man who becomes quickly enamored of her.

When she begins to sense she is going into labor, Yanka murders several other civilians, and is ordered by the parasite to steal a mobile blood donation van.

Police arrive at the scene and Yanka is rushed by ambulance toward the nearest hospital, but a medic confirms she has already died en route.

In the back of the ambulance, Yanka gives birth to a normal-looking baby boy, and is disturbed to find that the telepathic connection the two had during her pregnancy has been severed.

Yanka tries to warn the male passengers who taunt her, only to find moments later that the parasite, revealing its true form, has burrowed through the head of the driver.
