The Leopard Man is a 1943 American horror film directed by Jacques Tourneur, and starring Dennis O'Keefe, Jean Brooks, and Margo. Based on the book Black Alibi by Cornell Woolrich, it follows a series of violent murders in a town in New Mexico, which coincide with the escape of a leopard from a nightclub
It is one of the first American films to attempt an even remotely realistic portrayal of a serial killer (although that term had yet to be coined.
In an unnamed town in New Mexico, nightclub promoter Jerry Manning hires a black leopard as a publicity stunt for his girlfriend, Kiki Walker, a performer there. Kiki uses the opportunity to upstage the act of her rival, Clo-Clo, by making an entrance into the night club with the leopard on a leash. Angered, Clo-Clo frightens the leopard with her castanets, and it escapes, fleeing into the night. Charlie, the Native American owner of the leopard who leased it to Jerry, begins pestering him for money to replace the cat.

That night, Teresa, a young local woman, goes to purchase corn meal for her family's dinner. Under a bridge in an arroyo, she encounters the leopard and flees to her house. She is killed at the door just before her family is able to let her back in the house. The medical examiner rules Teresa's death an accident, concluding she was mauled by the leopard.

After, she visits Maria, a fortune teller, who warns her that "something black" is coming to claim her. En route home, Clo-Clo loses the $100 bill. When she goes back out to find it, she is attacked and murdered.

Kiki and Jerry prepare to leave for Chicago, coinciding with an annual procession that occurs in the town, commemorating a massacre of Native Americans by the Conquistadors. As they depart for their train, Kiki and Jerry are given a bouquet of flowers from Galbraith, which Kiki wishes to place on Consuelo's grave before they leave town. At the cemetery, they are met by Charlie, who notifies them his leopard has been found shot dead in the arroyo, and its fur taken; he presumes the cat has been dead for at least a week, suggesting a etc
