A wildly western adventure about five sheep, one mad professor and a quest to save all of sheepdom. A strange monster called Red Tongue has threatened all Rams, Ewes and Lambs. The Warrior Sheep know it's up to them to stop him. Last time they saved the Sheep God. This time they have to save all of sheepdom. ‘We did it once, we can do it again,' Wills the lamb says. And so the Warrior Sheep go West! To America, to the desert and the hot air of Las Vegas. But they have a crazy scientist following them, and Tod and Gran have been slung in jail by an over-zealous Sheriff. Can the Warriors give Professor Boomberg the slip and stop the sheep-killing monster? They'll need to hoof it, before Red Tongue tramples all over America…
