When five kids are invited to a cemetery at midnight, they think it's just a prank. When they find a gravestone that instructs them to dig up a grave, they think it's just a joke.It's no joke.An evil force is unleashed - a force that takes the shape of their worst fears.A shark in the water.A ghost in the walls.A nightmare of being buried alive.A snake about to strike.A sinister clown waiting in the woods.Once these fears are released, they won't go away. Not without a fight. . . .
