Witchcraft XI: Sisters in Blood

The three Catholic college students Colleen, Keri, and Maria agree to perform a ritual they believe is only a fake method acting exercise for a Macbeth production. Unknown to them, the school’s director Ramsden and Keri are actually Satanists who plan to resurrect the Sinobia sisters by channeling their spirits into the students.

The director Ramsden and Keri are revealed to be Satanists with real intent to resurrect the Sinobia sisters. They intend to channel the spirits through the students during the ritual, essentially using the actors as host bodies.

Maria becomes the first possessed by one of the 300-year-dead witches. She begins a brutal murder spree as the possession takes hold and searches for the stone key that serves as a portal for Abaddon.

Maria lures a fraternity boy to the cemetery where the ritual was performed and kills him. The brutal act signals the emergence of a real occult threat on the campus.

The murders draw LAPD Detectives Lutz and Garner, who handle odd cases for the department. They begin investigating, but Maria manages to throw them off the trail early on.

Maria's possession causes Keri to become possessed as well, and together they kill a priest who refuses to help locate the stone key.

Will Spanner, the warlock and Colleen's fiancé, uses his powers to sense rising evil on campus. He conducts investigative work and discovers the Sinobia sisters have possessed the three actresses.

The witches sacrifice the director to speed Abaddon's arrival. With the director gone, they gain leverage and push the demonic event forward.

One nun on campus holds the literal stone key to hell; Spanner learns of the key's location. His pursuit is aided by Sister Seraphina, but the witches kill her to seize the key.

The death of Sister Seraphina shocks the campus and compounds the crisis as the key falls into the witches' hands.

Rising death toll drives the evacuation of the campus; emergency crews order students and faculty to leave. The school becomes a ghost town as the situation escalates.

Colleen is possessed, giving the witches an additional body to help open the portal to hell. The threat expands beyond the initial trio as more bodies become vessels.

Lutz, Garner, Keli and Spanner follow the witches back into the cemetery; the group is separated and attacked, setting up the climactic confrontation.

Abaddon attempts to seduce Will; Garner and Lutz help Will resist, and together they thwart Satan's plan to return. The heroes manage to prevent the demon’s arrival and save the world.
