Blood Harvest is a taut drama starring Tiny Tim in his first dramatic film role. The story follows a beautiful young girl named Jill Robinson who returns to her peaceful rural hometown only to find her life turned upside down.
The house she grew up in has been defaced, her parents are missing, and the whole town hates her father, the bank supervisor who had foreclosed on many of the local farms. The only person who seems happy to see her is Marvelous Mervo (played by Tiny Tim), who wanders around the community dressed in a clown's suit with a grotesque clown's permanent grin painted on his face.
Mervo's brother tries to rekindle his love affair with Jill, but soon, those closest to her start being slaughtered like cattle, tied upside down from the rafters of the barn. The surprise ending reveals the madman behind the killings and a very unlikely savior.
