Paris, 19th century. A man who has been raised by wolves works at a zoo. But on full moon nights he transforms into a dangerous beast. Professor Paul is in charge of hunting him down as the young man develops an obsession for a prostitute.

A travelling circus in 19th century France adopts and showcases a feral "wolf boy", who grows into adulthood only to kill the one-man band. He runs off to Paris, where he develops a jealous, overprotective crush on a prostitute, leading him to attack her client, incurring a pursuit by a determined police surgeon.—Brian J.

A baby is brought up by wolves after they kill his parents. As a lad he is taken in by a second-rate travelling show, but one night when he is older he kills one of the troupe and runs away to Paris. Here he gets a job in a rundown zoo and falls for a girl who works in the local brothel. He resents her clients and whenever the moon is full gets extremely unpleasant about it.—Jeremy Perkins {J-26}
