Movie plot title: Black Sheep Movie plot: A young Henry Oldfield (Nick Fenton) lives on a sheep farm in New Zealand, with his father and older brother, Angus. After witnessing his father's pride on Henry's natural ability at farming, Angus plays a cruel prank on him involving the bloody corpse of his pet sheep, just moments before Mrs. Mac, the farm's housekeeper, comes to tell the boys that their father has been killed in an accident. The combined shock of these two incidents leads Henry to develop a crippling phobia of sheep. Fifteen years later, Henry (Nathan Meister) returns home to sell his share of the family farm to Angus (Peter Feeney). Unknown to Henry, Angus is carrying out secret genetic experiments that transform sheep from docile vegetarians into ferocious carnivores whose bite can transform a human into a bloodthirsty demonic half-sheep monstrosity. While trying to expose Angus's experiments, a pair of environmental activists named Grant (Oliver Driver) and Experience (Danielle Mason) accidentally release a mutant lamb. As Grant and Experience flee from the scientists, the lamb bites Grant and infects him. The lamb then escapes into the fields and infects the flocks of sheep. Meanwhile, Henry and an old friend, Tucker (Tammy Davis), decide to take a drive on the farm. Tucker sees a sheep that refuses to run away. At the same time, Experience steals a rifle from the car to try to shoot them. They eventually team up with each other to investigate a farm house that has smoke pouring out of it. Inside they find the mutilated body of a farmer. Henry sees a sheep in the hallway and, because of his phobia, he quietly shuts the door and locks it. The sheep tries to crash through the door. Tucker shoots the sheep. On the other end of the farm, Angus is driving around when he sees Grant. Grant bites Angus and runs off. Back in the car, Tucker, Experience, and Henry leave to warn Angus about the killer sheep, but a sheep hiding in the car bites Tucker. After the car is destroyed, they seek refuge in the laboratory. Henry and Tucker finally realize...
