Raven's Hollow.

On Halloween night, a rural ghost story comes true... Billy, his sister Lisa, and her boyfriend Mike, spend a night at the drive-in after trick or treating on Halloween. When Billy threatens to walk home through an old cornfield, Mike tells him a legend of Old Farmer Blood, who is said to have seeded his field with the blood of murder victims. When Billy disbelieves, Mike leads the trio into a nightmare of unrelenting terror.
