Panther is a semi-historic film about the origins of The Black Panther Party for Self-Defense. The movie spans about 3 years (1966-68) of the Black Panther's history in Oakland. Panther also uses historical footage (B/W) to emphasize some points.
After being implicated in a murder, a young woman flees New York City and moves to Los Angeles, where she rents a room from a writer. They begin an affair, but it seems she's been followed by a homicidal duplicate of herself.
