It’s typical mad scientist stuff.

Man turns sheep into bloodthirsty carnivore

Sheep bites man

Man mutates into man-sheep hybrid

Evil scientist is eaten by man-sheep hybrid

Such is the way of the world.

Also, if you enjoy good-bad movies, this is up there with killer clowns from outer space. It’s extremely enjoyable if you like campy bullshit.

They’re actually more zombie sheep, but there is a sheep-man hybrid.

Great film, I strongly recommend. It’s deliberately in the style of early Peter Jackson, even using Weta for the effects.
