Mitch and Ryan head out in the ocean to a oil rig abandoned after a strange accident and find a drifting yacht with a terrified young woman aboard who says that her yacht captain was pulled off the ship by a gelatinous green sea monster, which in fact was the result of the oil rig accident.

After a report of a possible black arts event in the nearby woods, Mitch and Ryan investigate and find a half-burned book containing strange incantations. Their search leads them to a specialty occult book shop where they find a duplicate of the book where the incantations are shown for calling evil spirits.
