PRINCE OF DARKNESS DEWSTRR

When the guardian priest of an abandoned church in Los Angeles dies, Father Loomis finds a diary and a key, opens the door of the basement and finds a cylinder with a gruesome green fluid. The priest contacts Professor Howard Birack in the local university and he invites a team of students to research the findings and translate manuscripts. The group discovers that the liquid is the essence of evil, actually Satan's remains, and has been kept locked in the church for centuries. Their research awakes the son of the Devil and when the student Susan Cabot gets close to the container, she drinks a jet of the green liquid, transforming in a living dead. Susan spreads the liquid among her friends, increasing the army of evil zombies. While the group is attacked inside the church by the zombies, homeless surround the church trapping them inside, and Satan tries to bring his father to the world.
