1987. All the teens in the small town of Barbara Falls are ready to make their prom night an evening they'll never forget.

But this year, the prom will have an unexpected visitor. A man escaped from ten years in solitary confinement. A murderous killer whose lust for blood knows no bounds.

And that's not the only surprise awaiting them tonight. It will indeed be an unforgettable night... if anybody lives to see tomorrow.

There will be screams. There will be blood. There will be promicide.
