At Mossy Bottom Farm, Shaun is no ordinary sheep. Cheeky, clever and always ready with a prank, he leads the flock into slapstick trouble while thinking and acting more like a person than a barnyard animal. As the oblivious Farmer goes about his day, grumpy sheepdog Bitzer tries to keep Shaun and the others in line, even as their mischief turns farm life into one big, chaotic family routine.
