Black Sheep

Terrified of sheep and dosed up on therapy, Henry Oldfield returns to his family's farm to sell out to his older brother Angus, unaware that something baaaad is going on: Angus' reckless gentic engineering program. When a pair of inept environmental activists release a mutant lamb from Angus' laboratory onto the farm, thousands of cuddly sheep are turned into bloodthirsty predators.
