Driven by pure vengeance, the unholy nun, Mother Mary, makes a bloody human sacrifice to summon the Devil, and then, dumps the body into a lake near a small village. As evil itself takes the form of a ferocious great white shark with glowing eyes, people go missing, and an unsuspecting inhabitant starts acting strangely. Now, the Catholic priest, Father Michael, has to do battle with the aquatic personification of the son of darkness and try to save the community before it's too late. Can the shark exorcist thwart the plans of Satan?
