The Tragic Beginning: The film opens with a ninja assassin known as Black Ninja, who is being pursued by the police after committing a series of murders. He is eventually cornered and wounded in a standoff. Before he dies, the ninja performs a ritual, transferring his soul and supernatural powers into a woman named Christie (played by Lucinda Dickey), a fitness instructor.
Possession Takes Over: After the ritual, Christie begins to experience strange and violent behavior, including uncontrollable fits of rage and killing people. Her actions are driven by the spirit of Black Ninja, and she starts to lose control of her body. The police, led by a detective named Billy Secord, begin investigating the gruesome murders tied to her.
The Battle with the Past: Billy, who becomes romantically involved with Christie, tries to help her break free from the possession. As he uncovers the truth about Black Ninja and Christie’s connection to him, he realizes that they must confront the supernatural force within her. The battle against the spirit becomes more intense, as Christie struggles with her inner conflict.
Final Showdown and Resolution: Billy, with the help of a martial arts expert who once trained with Black Ninja, devises a plan to exorcise the spirit from Christie. In a climactic battle, Billy defeats Black Ninja’s spirit, saving Christie. However, the film ends on an ambiguous note, leaving the fate of Christie uncertain and hinting that the spirit may not be entirely gone.
